* feat: add possibility of adding WebAuthn security keys to use as 2FA
This adds a basic UI for enabling WebAuthn 2FA. We did a little refactor
to the Settings page for editing the 2FA methods – now it will list the
methods that are available to the user (TOTP and WebAuthn) and from
there they'll be able to add or remove any of them.
Also, it's worth mentioning that for enabling WebAuthn it's required to
have TOTP enabled, so the first time that you go to the 2FA Settings
page, you'll be asked to set it up.
This work was inspired by the one donde by Github in their platform, and
despite it could be approached in different ways, we decided to go with
this one given that we feel that this gives a great UX.

* feat: add request for WebAuthn as second factor at login if enabled
This commits adds the feature for using WebAuthn as a second factor for
login when enabled.
If users have WebAuthn enabled, now a page requesting for the use of a
WebAuthn credential for log in will appear, although a link redirecting
to the old page for logging in using a two-factor code will also be
present.

* feat: disable WebAuthn when an Admin disables 2FA for a user
Co-authored-by: Facundo Padula <facundo.padula@cedarcode.com>
* feat: remove ability to disable TOTP leaving only WebAuthn as 2FA
Following examples form other platforms like Github, we decided to make
Webauthn 2FA secondary to 2FA with TOTP, so that we removed the
possibility of removing TOTP authentication only, leaving users with
just WEbAuthn as 2FA. Instead, users will have to click on 'Disable 2FA'
in order to remove second factor auth.
The reason for WebAuthn being secondary to TOPT is that in that way,
users will still be able to log in using their code from their phone's
application if they don't have their security keys with them – or maybe
even lost them.
* We had to change a little the flow for setting up TOTP, given that now
it's possible to setting up again if you already had TOTP, in order to
let users modify their authenticator app – given that now it's not
possible for them to disable TOTP and set it up again with another
authenticator app.
So, basically, now instead of storing the new `otp_secret` in the
user, we store it in the session until the process of set up is
finished.
This was because, as it was before, when users clicked on 'Edit' in
the new two-factor methods lists page, but then went back without
finishing the flow, their `otp_secret` had been changed therefore
invalidating their previous authenticator app, making them unable to
log in again using TOTP.

* refactor: fix eslint errors
The PR build was failing given that linting returning some errors.
This commit attempts to fix them.
* refactor: normalize i18n translations
The build was failing given that i18n translations files were not
normalized.
This commits fixes that.
* refactor: avoid having the webauthn gem locked to a specific version
* refactor: use symbols for routes without '/'
* refactor: avoid sending webauthn disabled email when 2FA is disabled
When an admins disable 2FA for users, we were sending two mails
to them, one notifying that 2FA was disabled and the other to notify
that WebAuthn was disabled.
As the second one is redundant since the first email includes it, we can
remove it and send just one email to users.
* refactor: avoid creating new env variable for webauthn_origin config

* Increase DNS timeout from 1 second to 5 seconds for MX check
1 seconds is rather short when using a recursive DNS resolver which
hasn't got a cached result already available. Use 5 seconds instead,
which is the timeout value we use for outgoing HTTP queries.
* Add more precise error messages for invalid e-mail addresses
Some translations of that string are single-line, which somehow seems to make
Crowdin issue a blank newline at the end of those translations.
This, in turns, leads to different results when running “i18n-tasks normalize”
depending on the version of libyaml installed, making the CI fail if it
runs a different version than whoever ran “i18n-tasks normalize”.
Since there is no real reason for that source string to be multi-line (it is
only displayed in HTML, without replacing newlines by <br/> tags),
attempt to fix Crowdin export by making the source string single-line.
* Change move handler to carry blocks and mutes over
When user A blocks user B and B moves to a new account C, make A block C

This commit:
- Refactors centered text blocks currently used for placeholders
for empty tables and puts styles for it in separate class -
.centered-text, simply aliasing text-align: center. Which is
furtherly used in this commit.
- Improves applications settings page to use heading actions, moving
"New application" button there, and displaying placeholder "You
have no applications" in place of empty table.
- Improves custom emoji settings page to use heading action
for "Upload" button, making it more easily accessible without
need to scroll through all of the emojis.
- Improves email domain blocks settings page, moving "Add new" to the
heading actions and using placeholder "No e-mail domains currently
blacklisted" instead of showing empty table.
When you have many filters, it may be hard for you to reach the button
to create yet another one. This commit moves creation button to the
heading, leaving the page just for the list.
On the other hand, when there are no filters, page looks kind of
strange with the empty table. So text stating obvious fact that user
has no filters was added in this commit too.
Closes#11020Closes#12790
This commit adds promotional notice on appearance settings about
translation project if any other locale than English is used. It
allows users to learn and contribute translations to Mastodon.
Step ahead, in this commit one unusual string is added - link to a
guide. By default it refers to Crowdin project itself, but if any of
Mastodon localization teams established their own guide, they can
refer it. Or, if Crowdin supports localized domain for language, it
can also be put there (e.g. https://fr.crowdin.com/...).
Currently the page re-uses strings from other contexts which doesn't fit
very well - strings incorrectly lowercase-d and pluralized, when they
don't need to be, because it's a table.
This commit changes page to re-use accounts.posts_tab_heading for toots,
and admin.accounts for "Following" and "Follows". This all should look
more aesthetically pleasing.
* Remove unused “salmon_url” string
* Remove more unused translatable strings
The following strings all used to be on the admin account page
but aren't used anymore: profile_url, outbox_url, followers_url, feed_url
Pluralize function from Rails framework does not work with other
languages than English, moreover it does not even work properly with
English [1]. Not that the latest applies to this context, it's just
a sign that we best to avoid this function, especially when there are
more reliable ways.
This commit changes how reports pages generated in order to avoid usage
of pluralize function, replacing it with default translation function,
called with given counter. On top of that, we have to make strings
pluralizable, so have to change locale files.

* Delete display_name method
Before this moment relationships managing page was using strings from
other context - from counters, but in order for translators to be able
to translate it relatively to the page, it must use separate strings.
I've split the strings for "Following" and "Followers" and put them to
"relationships" keyset in localization file. This should solve this
issue.

Regression from f371b32
Fix Tag#discoverable not returning tags where listable is nil instead of true
Add notice when saving hashtags in admin UI
Change public hashtag and directory pages to return 404 for forbidden tags
* Remove unused locale string
Fix#271
Add back the `GET /api/v1/trends` API with the caveat that it does
not return tags that have not been allowed to trend by the staff.
When a hashtag begins to trend (internally) and that hashtag has
not been previously reviewed by the staff, the staff is notified.
The new admin UI for hashtags allows filtering hashtags by where
they are used (e.g. in the profile directory), whether they have
been reviewed or are pending reviewal, they show by how many people
the hashtag is used in the directory, how many people used it
today, how many statuses with it have been created today, and it
allows fixing the name of the hashtag to make it more readable.
The disallowed hashtags feature has been reworked. It is now
controlled from the admin UI for hashtags instead of from
the file `config/settings.yml`
Allow access to account settings, 2FA, authorized applications, and
account deletions to unconfirmed and pending users, as well as
users who had their accounts disabled. Suspended users cannot update
their e-mail or password or delete their account.
Display account status on account settings page, for example, when
an account is frozen, limited, unconfirmed or pending review.
After sign up, login users straight away and show a simple page that
tells them the status of their account with links to account settings
and logout, to reduce onboarding friction and allow users to correct
wrongly typed e-mail addresses.
Move the final sign-up step of SSO integrations to be the same
as above to reduce code duplication.

* Remove obsolete strings
* Add local followers page to admin account UI
For moderation, I often find myself wondering who, locally, is following
a remote user. Currently, to see this, I have to go back to the web UI,
paste in their full handle, click their profile, and go to the
"Followers" tab (plus, this information is incidental, and if mastodon
ever decides to resolve all of the follower information, there will be
no place local followers are shown). This PR adds a new page which is
accessible via the "following" count on the admin's account view
page, which shows the local followers. (It has filter parameters for
account location to indicate that only local followers are shown, and
leave room for expansion if mastodon ever decides to store the entire
remote follow list).
* Normalize en.yml
* Add moderation warnings
Replace individual routes for disabling, silencing, and suspending
a user, as well as the report update route, with a unified account
action controller that allows you to select an action (none,
disable, silence, suspend) as well as whether it should generate an
e-mail notification with optional custom text. That notification,
with the optional custom text, is saved as a warning.
Additionally, there are warning presets you can configure to save
time when performing the above.

> Good lord what is happening in there
Previously the contents of the Web Push API payloads closely resembled the structure of JavaScript's [Notification](https://developer.mozilla.org/en-US/docs/Web/API/Notification). But now that the API is open to non-browser apps, and given that there is no required coupling between contents of the payload and a Notification object, here is how I changed the payload:
```json
{
"access_token": "...",
"preferred_locale": "en",
"notification_id": "12345",
"notification_type": "follow",
"title": "So and so followed you",
"body": "This is my bio",
"icon": "https://example.com/avatar.png"
}
```
The title, body and icon attributes are included as a fallback so you can construct a minimal notification if you cannot perform a network request to the API to get more data.
