* Add missing specs for relay accept/reject

* Display pending message on admin relays UI

On my local instance (https://ruby.social) we have a custom emoji for octocat (:octocat:). I would love to be able to use the emoji in the metadata for my profile. Instead of:

| github | https://github.com/phaedryx

It could be:

| :octocat: | https://github.com/phaedryx

(using a single emoji makes it easier to read the urls)

Add forgotten custom CSS admin setting strings

* Pass through video description as necessary.

* Add title to video, matching aria-label.

Fix #3894

Fix #8393

* Add default_settings class method to ScopedSettings

ScopedSettings was extended to use value of unscoped setting instead of
only using defaults set in config/settings.yml for selected settings.
This adds possibility for admins to set default values of users' settings,
for example default theme (as requested in #7092).

* Add ability to change an instance default theme

Closes #7092

Since that colorscheme is apparently broken for some colorblind people.

* Use HTML5's details and summary for statuses with CWs in admin interface

* Show exact number of followers/statuses on export page/in tooltip

* Fix tests

Follow-up to #8142

* Add separate setting for sidebar text (site_short_description)

* Fix tests

Upstream's implementation has been merged a while ago and is the preferred
way to set fields, as it is the only one compatible with upstream and is
more user-friendly.

sign up prompt to the remote follow modal

* Add keyword filtering

    GET|POST       /api/v1/filters
    GET|PUT|DELETE /api/v1/filters/:id

- Irreversible filters can drop toots from home or notifications
- Other filters can hide toots through the client app
- Filters use a phrase valid in particular contexts, expiration

* Make sure expired filters don't get applied client-side

* Add tests

* Add test for FeedManager

This is a bit hackish. The best way would simply to somehow
use Mastodon's ApplicationController with `use_pack 'error'` from
the Rake task, but I'm not sure how to do that.

* Add preference to hide following/followers lists

- Public pages
- ActivityPub collections (does not return pages but does give total)
- REST API (unless it's your own) (does not federate)

Fix #6901
