maziggy be7e85344c fix(finish-photo): drive capture from stg_cur=22, drop dispatch force-on (#1721)
capture_finish_photo (default-on) was forcing the timelapse MQTT field to
  true on every print, even when the user explicitly unchecked Timelapse in
  the slicer send dialog. On profiles with Timelapse Type = Smooth, that
  flipped the printer's timelapse_record_flag and un-gated the per-layer
  M622 J1 wipe blocks the slicer had baked in — toolhead parked off the
  part every layer, on prints the user opted out of recording.

  Root cause: #1397 implemented the finish-photo feature as a side channel
  of "force the printer into timelapse-recording mode at dispatch" so the
  last-frame extractor had a video to pull from. That conflated recording a
  timelapse with snapping a finish photo, and the per-layer side effects
  were decided at slice time by the user's timelapse_type, which Bambuddy
  has no visibility into post-slice.

  Fix: replace the force-on with a clean MQTT-state-driven trigger.

    bambu_mqtt.py fires a new on_finish_photo_moment callback when
    stg_cur transitions INTO 22 ("Filament unloading") while
    _was_running AND end-of-print gate matches (progress >= 99 OR
    layer_num >= total_layers OR remaining_time <= 0). The gate
    disambiguates from mid-print color swaps (which also transit
    stage 22 but at progress < 99). FINISH-state fallback in the same
    handler fires the callback at the existing transition if stage 22
    never arrived (cancel, external-spool-only, HMS halt, firmware
    variants).

    main.py registers on_finish_photo_moment as a top-level handler.
    It pre-captures one camera frame at the trigger edge (external cam
    → buffered RTSP → fresh RTSP via capture_camera_frame_bytes) and
    caches the JPEG bytes in _stage22_finish_frames[printer_id].
    _background_finish_photo consumes the cached bytes before its
    existing live-grab chain, so the saved photo has the better
    framing (toolhead parked, before bed drop) without restructuring
    the archive-resolution / fallback / notification wiring.

    When a timelapse IS actively recording (user explicitly opted in),
    pre-capture is skipped — _capture_finish_photo_from_timelapse
    still extracts the last frame, which is still the best framing
    and now has no force-on side effects because the user wanted the
    video.

  Removed: resolve_effective_timelapse, _resolve_effective_timelapse
  wrapper, both background_dispatch call sites, the print_scheduler call
  site, the archive.bambuddy_forced_timelapse write, _cleanup_forced_timelapse
  (~75 lines including the FTP-DELE walk across /timelapse, /timelapse/video,
  /record, /recording) and its call site. All paths now read
  bool(item.timelapse) / bool(job.options.get("timelapse", False)) directly.
  The archive.bambuddy_forced_timelapse DB column stays defined (default
  False) for back-compat with existing rows — no consumer reads it anymore.
