Bug from screenshot: trim bar visible but red handles not showing.
Causes:
1. video_duration in job is None for old jobs (was not saved on initial
processing). Without it, fallback was endInit+60 which placed handles
off-screen.
2. videoDuration was const, couldn't be updated when video metadata loads.
3. Handle offset was 9px but handles are now 24px wide (need 12px offset).
Fixes:
- Backend /api/transcript: fallback to last segment end time if
video_duration missing in job
- Frontend: videoDuration is let, updated on loadedmetadata
- Handle offset 9px → 12px for 24px wide handles
- Re-render trim after metadata loads to pick up actual video.duration
