Merge branch 'main' into glitch-soc/merge-upstream

Conflicts:
- `app/controllers/settings/preferences_controller.rb`:
  Conflicts due to us having more user settings and upstream dropping
  `hide_network` (to replace it with an account attribute, properly migrated).
  Dropped `hide_network` like upstream.
- `app/lib/user_settings_decorator.rb`:
  Conflicts due to us having more user settings and upstream dropping
  `hide_network` (to replace it with an account attribute, properly migrated).
  Dropped `hide_network` like upstream.
- `app/models/status.rb`:
  Conflict because of slight change in how glitch-soc handles the scope to
  filter out local-only posts for anonymous viewers.
  Took upstream's changes and re-applied glitch-soc's change.
- `app/models/user.rb`:
  Conflicts due to us having more user settings and upstream dropping
  `hide_network` (to replace it with an account attribute, properly migrated).
  Dropped `hide_network` like upstream.
- `app/views/directories/index.html.haml`:
  Conflict because upstream redesigned that page while glitch-soc had a minor
  change to support hiding the number of followers.
  Ported glitch-soc's change on top of upstream's redesign.

Additional changes:
- `app/models/account_statuses_filter.rb`:
  See change to `app/models/status.rb`.
