Adopt room info power levels (#4245)

* Use the newly RoomInfo published PowerLevels; update permissions at the same time as the room info and avoid unnecessary async calls.

* Introduce a RoomInfoProxyProtocol and associated mock and move away from mocked SDK RoomInfos

* Bump the SDK to v25.06.23

* Expose new non-throwing methods for checking one's own user permissions

* Fix the unit and preview tests (except the TimelineMediaPreviewDetails for which simplified snapshots were generated)

* Converge on one single implementation for computing a room's avatar.

* Fix more unit tests

* Fix the TimelineMediaPreviewDetailsView snapshot tests

This reverts commit 9b6c819e611ad2fa3de2c34a4a7aa556fc9faadd.
