Fix #2350

Fix #8918

Fix #9057

Fix #9034

Reminder: Suggestions were added in #7918 and are based on who you
interact with who you do not follow. E.g. if you boost someone a lot
from seeing other people's boosts of that person, it makes sense you
might be interested in following the original source; or if you reply
to someone a lot, maybe you'd want to follow them

Each suggestion can be dismissed

* RTL: remove blank character inside bdi

* Update app/javascript/mastodon/components/display_name.js

Co-Authored-By: mabkenar <ampbox@gmail.com>

Fixes #9045

* RTL: fix admin account avatar margin in about page

* fix code style

* Fix position of the domain label

* Fix position of the domain label for RTL

- Fix color mismatch of linear gradient which assigned to "::after" pseudo class

* Add "disable" button to report screen

* i18n-tasks remove-unused

* Do not show "limited" visibility in default visibility preference

Fix regression from #8950

* Fix code style issue

* Add silent column to mentions

* Save silent mentions in ActivityPub Create handler and optimize it

Move networking calls out of the database transaction

* Add "limited" visibility level masked as "private" in the API

Unlike DMs, limited statuses are pushed into home feeds. The access
control rules between direct and limited statuses is almost the same,
except for counter and conversation logic

* Ensure silent column is non-null, add spec

* Ensure filters don't check silent mentions for blocks/mutes

As those are "this person is also allowed to see" rather than "this
person is involved", therefore does not warrant filtering

* Clean up code

* Use Status#active_mentions to limit returned mentions

* Fix code style issues

* Use Status#active_mentions in Notification

And remove stream_entry eager-loading from Notification

This fixes hotkeys not working when pressing the column
“back” button, for instance.

Regression from #8569

Follow-up to #8766

Regression from #8942

* Downcase signed_headers string before building the signed string

The HTTP Signatures draft does not mandate the “headers” field to be downcased,
but mandates the header field names to be downcased in the signed string, which
means that prior to this patch, Mastodon could fail to process signatures from
some compliant clients. It also means that it would not actually check the
Digest of non-compliant clients that wouldn't use a lowercased Digest field
name.

Thankfully, I don't know of any such client.

* Revert "Remove dead code (#8919)"

This reverts commit a00ce8c92c.

* Restore time window checking, change it to 12 hours

By checking the Date header, we can prevent replaying old vulnerable
signatures. The focus is to prevent replaying old vulnerable requests
from software that has been fixed in the meantime, so a somewhat long
window should be fine and accounts for timezone misconfiguration.

* Escape users' URLs when formatting them

Fixes possible HTML injection

* Escape all string interpolations in Formatter class

Slightly improve performance by reducing class allocations
from repeated Formatter#encode calls

* Fix code style issues

* Set CSP rules in RoR's configuration

* Override CSP setting in the embed controller to allow frames

Regression from #8951

* Do not push DMs into the home feed

* Show DMs column after sending a DM, if DMs column is not already shown

Mention and emoji code may perform network calls, but does not need
to do that inside the database transaction. This may improve availability
of database connections when using pgBouncer in transaction mode.

Fix #8685

* cleanup pass

* undo mistakes

* fixed.
