Vadym Samoilenko c413fcb747 feat: add SDH (Subtitles for Deaf and Hard of Hearing) caption output
SDH captions extend standard VTT with speaker identification labels,
sound effects [PHONE RINGS], music notation ♪, and off-screen indicators.

- Add sdh_vtt flag to RequestedOutputs model and frontend form
- Add sdh_captions_vtt_gcs field to LangOutput model
- Inject SDH generation instructions into both Gemini prompts via
  {SDH_FIELD} and {SDH_GUIDELINES} placeholders when requested
- Upload sdh_captions.vtt to GCS in ingest task
- Pass SDH through video_native translation (Gemini generates it directly)
  and traditional translation (translate source SDH VTT via Gemini)
- Expose sdh_captions_vtt in downloads endpoint and bulk zip export
