- DM: add dl_missing_* fields to AppCtx for sequential queue
- DM player: count_missing_in_season, find_next_missing, download_episode, download_missing_season_start/next
- DM main onResult: auto-continue queue when dl_missing_active, updates status DL X/Y, finishes with done ok/fail
- SdDownloader: file exists returns true (Already on SD) with total=file size, not false
- SdDownloader: set_result_and_close minimal bundle (only success bool) to avoid internal heap OOM crash on close
- SdDownloader: Cancel button becomes Close after done, calls tt_app_stop() directly (manual close per request, auto-close unreliable)
- Fixes crash on close observed in demo mode (file exists) and after download done
Tested on 192.168.68.133: SdDownloader shows Already on SD + Close, DM shows S10 5/6 after sequential, no crash on open/close cycles
