Remove embedded music player

The music feature is retired: delete the Media tab, MediaAPI,
MediaPlayerController, PinnedMediaResourceLoader, MediaPanelView, the
media_state control publish, media scope handling in VoiceSession, the
volume setting, and all media tests. App is now Talk + Activity tabs.

Backend media API in hope-voice-api is untouched (still serves the web UI).

 ### Functional fixes
 
 - Observed nested transcript/state/task objects so asynchronous updates render.
-- Preserved latest-wins server replacement; clear old media when switching servers.
-- Sent standalone media controls and reports to the default server room.
-- Refreshed track metadata as downloads become ready; exposed request/decoder errors.
-- Loaded artwork through pinned TLS for the NAS self-signed certificate.
-- Requested cached AAC (`?format=m4a`) for YouTube library tracks on iOS.
-- Corrected AVFoundation's content type to a UTI rather than an HTTP MIME string.
-- Changed the pinned media loader to deliver 256 KB byte ranges instead of buffering
-  an entire song before delivering usable audio, addressing a reproduced timeout.
