Fix #6670

This is also implemented in Pawoo:
ceafdbd1bb

Previously the default locale was set by Localized concern for controllers,
but it was not enforced for mailers.

config is enforced throughout the application and an appropriate place to
set the default locale.

* Update remove_serializer.rb

* Update add_serializer.rb

* Update fetch_featured_collection_service.rb

Use Rails smart boolean cast to account for values such as "f",
"0", "false", etc. Previously, if a param was present in the request,
it would count as true.

It was merge when it needed to be deep_merge. And added some tests

* Fix #201: Account archive download

* Export actor and private key in the archive

* Optimize BackupService

- Add conversation to cached associations of status, because
  somehow it was forgotten and is source of N+1 queries
- Explicitly call GC between batches of records being fetched
  (Model class allocations are the worst offender)
- Stream media files into the tar in 1MB chunks
  (Do not allocate media file (up to 8MB) as string into memory)
- Use #bytesize instead of #size to calculate file size for JSON
  (Fix FileOverflow error)
- Segment media into subfolders by status ID because apparently
  GIF-to-MP4 media are all named "media.mp4" for some reason

* Keep uniquely generated filename in Paperclip::GifTranscoder

* Ensure dumped files do not overwrite each other by maintaing directory partitions

* Give tar archives a good name

* Add scheduler to remove week-old backups

* Fix code style issue

* Save metadata from video attachments, put correct dimensions into OG tags

* Add option to show only local toots in timeline preview
Right know, toots from all the known fediverse are shown in the main
page of an instance. That however doesn't reflect the instance itself.
With this option the admin may choose to display only local toots so
that users checking the instance get a better idea of internal
conversations.

UserTrackingConcern is circumvented by SessionsController#create
because it calls warden, which calls the User#update_tracked_fields!
method directly. Move returning user logic to that method.

The service used to be named ResolveRemoteAccountService resolves local
accounts as well.

* web share target

* fix

* fix

CSRF token checking was enabled for API controllers in #6223,
producing "Can't verify CSRF token authenticity" log spam. This
disables logging of failed CSRF checks.

This also changes the protection strategy for
PushSubscriptionsController to use exceptions, making it consistent
with other controllers that use sessions.

Also adds the ability to decouple the centralized axios logic from the
state dispatcher

Fixes #6197.

* Allow to dereference Follow object for ActivityPub

* Accept IRI as object representation for Accept activity

* Allow HTTP caching of json view of public statuses

HTML views are not cached as they can contain private statuses as well

* Disable session cookies for ActivityPub json rendering of public toots

* 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

* 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
