OTA: quiet the audio sources during a firmware upload

Browse Source 
An upload during an active Spotify session crawled (~10 kB/s, 197 s)
and ended in a reset (seen twice). Workaround:
- aes67_ota_on_update(cb): cb(true) right before an accepted upload
  writes flash, cb(false) if it then fails.
- The player pauses Spotify (spotify_pause -> SpircHandler::setPause, the
  app follows) and suspends HLS fetching (hls_suspend); resumed if the
  upload fails. AES67 TX keeps running (silence).
- Verified: upload during Spotify playback paused the session and
  installed in 25.8 s (normal for 2 MB), clean reboot and self-test.
  Root cause still open (noted in CLAUDE.md with the other cspot items).

- Download speed ~1.4 Mbit/s over TLS (fine for ~250 kbit/s; tune buffer sizes / per-chunk overhead).
- Not yet tested: HE-AAC variant (140k), other stations, fMP4/ADTS-only playlists, discontinuities (#EXT-X-DISCONTINUITY), network loss and recovery, long runs.
- Audio starts only after PTP lock (~20 s after boot): intended, TX needs PTP.

- OTA during an active Spotify session made the upload crawl (~10 kB/s) and ended in a reset; worked around by pausing Spotify / suspending HLS for the upload (aes67_ota_on_update). Root cause not found (suspect: flash writes stall PSRAM-heavy tasks). Watch for similar stalls.
- First connects sometimes fail ("Can't connect to spotify servers"), a retry works.
- Internal heap drops from ~408 KB to ~232 KB with a session; check what can move to PSRAM.
- source.mode changes only start/stop Spotify at boot; in hls mode a running session's audio is dropped (it races through the queue).
- Mute at 0 % volume not yet confirmed.
- [ ] failover (auto mode) + /api/player
- [ ] 8. Mono sum, gain, polish.
