Breaking changes addressed:
* Make `MatrixClient.getNotificationSettings()` async, cache its result.
* Use `RoomInfo` for accessing the updated room's info.
* Refactor `MatrixRoom` so it always receives an initial `MatrixRoomInfo` value: this value will be used to make `MatrixRoom.roomInfoFlow` a `StateFlow` so we can assume the initial updated Room data will be present.
* Fetch encryption state when loading a room if it's unknown
This should trigger when getting close the start of the loaded timeline, making scrolling back smoother, specially when combined with the persistent event cache.
* Move `observeRoomMemberIdentityStateChange` and associated classes to `libs:matrixui` module so they can be reused
* Add `EncryptionService.getUserIdentity` method to retrieve not only if the user is verified or not, but in which state they are
* Fix `IdentityChangePresenter` after the previous changes
* Fix `withFakeLifecycleOwner` and add `testWithLifecycleOwner` helper
* Display verified badge in DM top app bar when possible
* Display a verification violation warning icon next to the 'People' item in room details screen
* Display either a verified badge or a verification violation warning icon next to the room members in the room member list screen
* Display either a verified badge or a verification violation warning and withdraw verification button in the room member profile.
Generic user profiles won't display verification state anymore since we can't easily track changes in it.
* Add preview for room member details screen with verification violation identity state
* Add verified and violation badge to the `Profile` list item in room details screen
* Update screenshots

* Add support for starting verification of a user
* Add support for replying to incoming user verification requests
* Add reset recovery key button and previews to `ChooseSelfVerificationModeView`
* Add 'Profile' item in room details screen
* Update screenshots
* Remove `showDeviceVerifiedScreen` parameter from `NavTarget.UseAnotherDevice`
* Allow exiting the FTUE flow, which will close the app. The previous state will be restored when the app is reopened.
* When outgoing verification fails, move to the `Canceled` state. Then, when resetting the state machine state also reset the verification service.
