fix: toggle preview display bug, add job deletion, optimize pipeline
- Fix: toggle ON now resets img display to block (was stuck on 'waiting')
- Toggle OFF sends API call to stop preview file writes
- Delete button on status page + jobs page cards
- DELETE /api/jobs/<id> endpoint removes job + output files
- PUT /api/jobs/<id>/preview endpoint toggles preview_enabled
- Pipeline skips resize/encode/write when preview_enabled=False
- Reduced preview defaults: 480px max, JPEG quality 60
- 62/62 tests pass
