Add an extension for room details sections (#7781)

* Add an extension for room details sections

Provide a no-op rendering hook for build-specific room details sections and shared room audio labels. Keep the default room details behavior unchanged.

* Cover the default room details extension

Verify that the no-op extension renders no content and leaves surrounding UI unchanged through recomposition. Cover its constructor and both generated render paths.

* Refine the room details extension and link the enterprise picker

Expose ColumnScope to contributed room details sections and use room-details string keys. Pin the enterprise submodule to the reviewed picker implementation so integrated builds include it behind the default-off flag.

* Make the room details extension a functional interface

Declare the single composable rendering contract as a fun interface to satisfy the Sonar check while preserving its named dependency injection binding.

* Update localazy strings for the audio section in room details

* Bump enterprise commit
