Follows /api/player's position, moves on locally between polls while
playing, seeks on release; disabled when the source can't seek.

- Core config: cfg_mark_secret(group, key). GET /api/config returns ""
for secret keys; a POST with "" keeps the stored value, null clears it;
cfg_get() returns the real value. Documented in aes67-core-base.md.
- source.spotify_client_id / spotify_client_secret (secret write-only):
each user's own Spotify developer app, needed by the maintained cspot
fork (philippe44/cspot) since Spotify's 2025 API restrictions.
- UI: client ID field, password field for the secret ("leave empty to
keep"), link to developer.spotify.com; enabled for spotify/auto modes.
- status.spotify_state: "no client credentials" while either is missing.
- Verified: secret never appears in GET; UI-style re-save keeps it;
survives reboot; null clears it.

- main/audio_ring: SPSC ring of interleaved int32 frames in PSRAM
(4 s at 48 kHz stereo), lock-free with acquire/release counters; the
TX pull callback never blocks.
- main/player: source selection from source.mode and the pull callback
for aes67_tx. tone -> the core's PTP-phased 1 kHz tone; off -> silence;
hls/spotify -> ring with 1 s prefill (silence while buffering is not an
underrun; running dry is, and prefills again). Status fields
active_source, source_state, spotify_state, buffer_ms. source config
applies live.
- New source.mode "tone" (validation, UI dropdown, doc) for commissioning.
- Temporary 440 Hz producer in hls mode (until the HLS player exists).
- Verified: tone 999.7 Hz -18 dBFS; off silent; hls 440.0 Hz with max
sample step 60816 (ideal sine 60825, i.e. no discontinuities), buffer
3983 ms, 0 underruns; spotify silent/not implemented.
