feat(android): level playback with a gain processor in the audio sink (M464 #5000)

Media3 1.10.1 -> 1.11.0, the version Renovate proposes; 1.11 flushes the
sink's audio processors at every item boundary with the playlist timeline
and the new item's period. GainAudioProcessor uses that to find the track
and its play-order neighbours (auto mode's album rule) and applies the
gain from the first sample, gapless transitions included, with a -1 dBFS
peak limiter in limiter mode and a full-scale clamp otherwise.

Gains come from the library cache first (sync now carries track and album
ReplayGain values; Room v10 adds the columns and rewinds the sync cursor
so an existing cache re-pulls them), then GET /api/tracks/replay-gain,
then none. The player service refreshes the leveling preference at start.

Web: a same-album neighbour without a track number no longer counts as
in-order album play, matching Android.
