feat(p12-w2): track-cardinal high-res waveform fetch + bridge rewire

Browse Source 
Add GET api/track/{trackEntryKey}/waveform/high-res (+ proxy), ITrackDataService.GetTrackWaveform; rewire visualizer to resolve the current track's EntryKey and re-fetch on track change. Retire the client mix-waveform read path.

// GET api/release/{entryKey}/mix/waveform (unauthenticated)

// but reads the Mix's track datum from the track-waveforms vault. 404 when the release is not a Mix,
// carries no waveform key,
// or no datum is stored. Public read — addresses by the opaque EntryKey, not the int PK (§3e). The
// {entryKey} string segment cannot collide with the ApiKey-gated POST {id:long}/mix/waveform (different
// verb + constraint). Declared before the shorter "{entryKey}" route for clarity.

// LEGACY (phase-12 §5b): the visualizer no longer fetches through this release-addressed route — it
// resolves the current track's datum via the track-cardinal GET api/track/{trackEntryKey}/waveform/
// high-res. This endpoint is retained as a thin transitional delegate (it serves the identical datum,
// since a Mix is single-track) and has no client caller today; remove it once nothing depends on the
// release-addressed shape.
