* Add ability to mark statuses as sensitive from reports in admin UI

* Allow mark as sensitive action on statuses with preview cards

* Change old moderation strikes to be displayed in a separate page

Fixes #17552

This changes the moderation strikes displayed on `/auth/edit` to be those from
the past 3 months, and make all moderation strikes targeting the current user
available in `/disputes`.

* Add short description of what the strikes page is for

* Move link to list of strikes to “Account status” instead of navigation item

* Normalize i18n file

* Fix layout and styling of strikes link

* Revert highlights_on regexp

* Reintroduce account status summary

- this way, “Account status” is never empty
- account status is not necessarily bound to strikes, or recent strikes

* Add appeals

* Add ability to reject appeals and ability to browse pending appeals in admin UI

* Add strikes to account page in settings

* Various fixes and improvements

- Add separate notification setting for appeals, separate from reports
- Fix style of links in report/strike header
- Change approving an appeal to not restore statuses (due to federation complexities)
- Change style of successfully appealed strikes on account settings page
- Change account settings page to only show unappealed or recently appealed strikes

* Change appealed_at to overruled_at

* Fix missing method error

* Add account sensitized

* Fix i18n normalize

* Fix description and spec

* Fix spec

* Fix wording

* 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.

* Use Account#local_username_and_domain
