Fixes #8463

* rubocop: quit being so picky

* rubocop: miscellany

* rubocop: prefer present to blank

* Allow moderators to disable/enable login

* Instead of rejecting login, show forbidden error when login disabled

Avoid confusion because when login is rejected, the message is that
the account is not activated, which is wrong.

* Fix tests

* Unuse ActiveRecord::Base#cache_key

* Enable cache_versioning

* Call cache_collection

* Add option to not consider word boundaries when filtering phrases

* Add a few tests for keyword/phrase filtering

DELETE /api/v1/suggestions/:account_id

When blocking, remove suggestion from both sides. Muting not affected,
since muting is supposed to be invisible to the target.

* Add more granular OAuth scopes

* Add human-readable descriptions of the new scopes

* Ensure new scopes look good on the app UI

* Add tests

* Group scopes in screen and color-code dangerous ones

* Fix wrong extra scope

* Re-add follow recommendations API

    GET /api/v1/suggestions

Removed in 8efa081f21 due to Neo4J
dependency. The algorithm uses triadic closures, takes into account
suspensions, blocks, mutes, domain blocks, excludes locked and moved
accounts, and prefers more recently updated accounts.

* Track interactions with people you don't follow

Replying to, favouriting and reblogging someone you're not following
will make them show up in follow recommendations. The interactions
have different weights:

- Replying is 1
- Favouriting is 10 (decidedly positive interaction, but private)
- Reblogging is 20

Following them, muting or blocking will remove them from the list,
obviously.

* Remove triadic closures, ensure potential friendships are trimmed

* 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 missing API methods

* Remove "regex filter" from column settings

* Add tests

* Add test for FeedManager

* Add CustomFilter test

* Add UI for managing filters

* Add streaming API event to allow syncing filters

* Fix tests

* Allow selecting default posting language instead of auto-detect

* Enable default language setting in credentials API

* Fix form saving

* Send rejections to followers when user hides domain they're on

* Use account domain blocks for "authorized followers" action

Replace soft-blocking (block & unblock) behaviour with follow rejection

* Split sync and async work of account domain blocking

Do not create domain block when removing followers by domain, that
is probably unexpected from the user's perspective.

* Adjust confirmation message for domain block

* yarn manage:translations

* returns ActiveRecord.Relation in default behavor

* fix codestyle issue

* Track trending tags

- Half-life of 1 day
- Historical usage in daily buckets (last 7 days stored)
- GET /api/v1/trends

Fix #271

* Add trends to web UI

* Don't render compose form on search route, adjust search results header

* Disqualify tag from trends if it's in disallowed hashtags setting

* Count distinct accounts using tag, ignore silenced accounts

Fix #7557

* 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

* Add preference

* Add delegation

* Fix issue

* Fix issue

permitted_for scope is slow when combined with pinned status scope.
Fortunately permitted_for scope can safely be removed because a pinned
status is always public.

My bad...

* Add Api::V1::Push::SubscriptionsController#show

* Add to routes

- POST /api/v1/push/subscription
- PUT /api/v1/push/subscription
- DELETE /api/v1/push/subscription
- New OAuth scope: "push" (required for the above methods)

* Store actor type in database

* Add bot nameplate to web UI, add setting to preferences, API, AP
Fix #7365

* Replace ruby-oembed with FetchOEmbedService

Reduce startup by 45382 allocated objects

* Remove preloaded JSON-LD in favour of caching HTTP responses

Reduce boot RAM by about 6 MiB

* Fix tests

* Fix test suite by stubbing out JSON-LD contexts

Add raw bio fields to the source attribute on GET /api/v1/accounts/verify_credentials

Fix #7243

* Added a timeline for Direct statuses
* Lists all Direct statuses you've sent and received
* Displayed in Getting Started
* Streaming server support for direct TL

* Changes to match other timelines in 2.0

Bookmarks behave like favourites, except they aren't shared with other
users and do not have an associated counter.

This also limits the statuses returned by API, but pagination is not
implemented in Web API yet. I still expect it brings user experience
better than making a user wait to fetch all ancestor statuses and flooding
the column with them.

* Enable updating additional account information from user preferences via rest api
Resolves #6553

* Pacify rubocop

* Decoerce incoming settings in UserSettingsDecorator

* Create user preferences hash directly from incoming credentials instead of going through ActionController::Parameters

* Clean up user preferences update

* Use ActiveModel::Type::Boolean instead of manually checking stringified number equivalence

* Federate pinned statuses over ActivityPub

* Display pinned toots in web UI

Fix #6117

* Fix migration

* Fix tests

* Update outbox_serializer.rb

* 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.
