A change introduced in #6125 prevents
`Devise::Models::Confirmable#confirm` from being called for existing
users, which in turn leads to `email` not being set to
`unconfirmed_email`, breaking email updates. This also adds a test
that would've caught this issue.

Migration is wrapped by transaction, so manual `commit_db_transaction` without transaction restarting causes "there is no transaction in progress" warnings. We should use `disable_ddl_transaction!` instead, if we can omit transaction completely.

* Improve Traditional Chinese translations

* Sort alphabetically

without them, such as is the case with GNU social

Fixes the ability to find GNU social accounts via URL in search and
when using remote follow function

Though the subsections are representing features such as navigation and
settings, they are categorized by the ways how they are implemented
(internal navigation or external links.) They are irrelevant and some
arrangements were confusing because of that. (It is nonsense that instance
information is in settings subsection, for example.)

This fixes the issue by rearranging.

* new strings: hashtag+unlisted, mute, block

* Add confirmation step for email changes

* Add more instance stats APIs

* Don't normalize URLs in toots

URL normalization is ill-defined and may cause certain links to break.

* Change specs since we are not normalizing user-provided URLs

* Allow to dereference Follow object for ActivityPub

* Accept IRI as object representation for Accept activity

The background of the navigation matters because its scrollbar is
transparent.

* Sanitize classlist properly

* Actually properly sanitize every class after the first

* Improve Formatter spec to check for multiple classes and non-space whitespace

* Remove trailing whitespace

There's no reason for an Account record to persist after Delete->Actor is received. SuspendAccountService is necessary to make sure deleted toots get sent over streaming API properly and home feeds get cleaned up. By removing Account record, we can ensure that if in the future the account is restored remotely (or username reused), it can start with a clean slate.

yay for regexes, amirite

* Add confirmation step for email changes

This adds a confirmation step for email changes of existing users.
Like the initial account confirmation, a confirmation link is sent
to the new address.

Additionally, a notification is sent to the existing address when
the change is initiated. This message includes instruction to reset
the password immediately or to contact the instance admin if the
change was not initiated by the account owner.

Fixes #3871

* Add review fixes

* delete X-UA-Compatible

* undo

* restore

Serbian latin (sr-Latn) is generated automatically from Serbian (sr) translation. Also changed some wording in original (Serbian) translation.

* Adding Serbian translation

* i18n-tasks normalize

Relates to #6125, #6099

* Add GET /api/v1/instance/peers API to reveal known domains

* Add GET /api/v1/instance/activity API

* Make new APIs disableable, exclude private statuses from activity stats

* Fix code style issue

* Fix week timestamps

* Make host_meta/webfinger replies cacheable (fixes #6100)

Drop common code for handling users and sessions as webfinger queries
are very basic, public APIs.

Also explicitly mark results as cacheable with “expires_in”.

* Add “Vary: Accept” header for caching since content-negociation is used
