feat(audio): smart forward/backward seek with press-coalescing

Replace the ad-hoc 5-minute seek that commit 76e1535 bolted onto the
next/previous-track buttons (it overshot on VBR/FLAC, silently jumped to
the next track near a file boundary, and re-synced the decoder on every
single press so it felt sluggish and dropped presses).

- Revert NEXTTRACK/PREVIOUSTRACK to upstream behavior (incl. the
  "previous track only when <5s in, else restart" logic).
- Add CMD_SMART_FORWARDS/BACKWARDS (action codes 190/191) plus
  track-control codes SMARTFORWARD/SMARTBACKWARD (10/11). On a single
  long file they seek inside the file; on a multi-file playlist they fall
  back to next/previous track.
- Coalesce rapid presses: the offset accumulates and is applied once
  presses settle (smartSeekCoalesceMs), so the decoder re-syncs once
  instead of once per press.
- Step configurable in the web UI (General -> options -> "Smart seek
  step (sec.)", NVS key seekStep, default 300), applied live without a
  reboot. de/en/fr locales, Swagger general schema, and the GitHub-Pages
  demo mock updated.
- MQTT: smart seek works via the existing track-control topic (codes
  10/11); web/REST via the controls "action" command.

Built for the complete env and flashed/verified on device (the new
seekStep setting round-trips through /settings).

The resume now rewinds a few seconds and fades the volume up over that span, so the glitch lands on already-heard audio — no content lost, clean sound from where you stopped.

 | Audiobooks restart from the beginning after a long pause: if a position-saving audiobook card has not been played for a configurable span (new **"Restart audiobook after (hrs)"** general setting, default 24 h, 0 = off), the next tap starts the book over instead of resuming mid-chapter — handy for kids who no longer remember where they were. The per-card last-seen timestamp lives in its own NVS namespace and is only consulted when the clock is valid (NTP/RTC) | [`445e290`](../../commit/445e290) |
+| **Smart forward/backward seek with press-coalescing** (`CMD_SMART_FORWARDS` / `CMD_SMART_BACKWARDS`, action codes 190/191; also track-control codes 10/11 for MQTT): on an audiobook that is a single long file these commands seek *inside* the file; on a playlist of several files they fall back to next/previous track. Rapid presses are bundled into one jump so the decoder re-syncs once instead of once per press (the old per-press seek felt sluggish on FLAC and dropped presses during the multi-second resync). The step is configurable in the web UI (General → options → **"Smart seek step (sec.)"**, NVS key `seekStep`, default 300 s = 5 min). Bind them to physical buttons in the **Buttons** settings tab. The plain `CMD_SEEK_FORWARDS`/`BACKWARDS` 30 s jump (`jumpOffset`) and the upstream next/previous-track behavior are both unchanged | [`PENDING`](../../commit/PENDING) |
