feat(rework): synced subtitle extraction via file upload + Whisper, SRT export
Phase 1 of subtitle timeline studio. Upload a video in the rework editor →
proxy to Python /transcribe (faster-whisper) → store segments → render a
playback-synced segment list and export CapCut-importable SRT.
- ScriptSegment + SrtFormatter (pure, unit-tested) with speed rescaling
- ChannelVideoScript.segmentsJson column (ddl-auto adds it)
- ChannelService.transcribeFromFile + getSegments/parseSegments
- POST /{id}/transcribe (multipart), GET /{id}/script.srt?speed=, /script now returns segments
- rework.html: upload button, local <video>, segment list, SRT export + speed
- multipart 200MB limit; python.base-url config (PYTHON_BASE_URL)
- repo: findFirstByVideoIdOrderByIdDesc/findAllByVideoId (dedup-safe lookups)
