* Simplify how event content with captions are displayed
The caption component will now be added in `TimelineItemEventContentView` instead of separately in each `TimelineItem__View` component
* Make sure `CoilMediaFetcher` methods to fetch media throw errors
We need to catch them later to check if the content scanner marked some thumbnails or medias as invalid/unsafe in `AsyncImage` instances
* Add a `ContentScannerService` that allows us to manually scan a list of medias in an event and then update and store the results
The results take the form of `ContentValidationValue`, stored in a `ContentValidationState` instance tied to the event
* Create `EventContentValidationCache` to keep the `ContentValidationStates` for events in a room
* Expose `EventContentValidationCache` to Compose using `LocalEventContentValidationState`
Also add a couple of helper functions to avoid having to manually remember the states
* Use the new components to display invalid content in the timeline items
* Add `blurhash` to most media items so we can use it while validating the thumbnails/medias
* Fix custom layout issues with screenshot and UI tests
* Also check the validation state for replied-to events in the composer
* Fix and add tests
* Handle unrecoverable content validation errors too: display a 'not found' UI
* Improve the performance of `EqualWidthColumn` for the single item case
* Update screenshots

Publish the current queue head via a StateFlow so any host that subscribes
after a message is posted (e.g. a screen recomposing as a flow pops back to it)
still observes it. The previous mutex-gated flow delivered each message to a
single parked collector, which could starve the host actually on screen and
drop the snackbar. Adds a regression test for the late-subscriber case.

Extract the show/hide password trailing-icon into a reusable
PasswordVisibilityToggle so every password field reveals plaintext the
same way and announces the same a11y labels. Reuse it from the login and
reset-identity password fields. Pure refactor, no behaviour change.

Add threads list screen for rooms:
- Add `ThreadsListService` to subscribe to thread changes in the room.
- Create `ThreadsListView` and its associated node a presenters (the UI may change).
- Add a menu icon in the room screen to open it.
This is still pending info about unread threads, so several UI components related to it will be hidden.
* Add feature flag and use it to hide the access to this new screen
