Blocks 1–5 of stabilization plan:
SECURITY
- validation.py: restore settings.upload_max_video_bytes (T-14 regression fix)
and JSON object key validation that was incorrectly removed
- MT-18: add accessible_org_ids filter to list_for_reviewer/list_for_linguist
so reviewers/linguists only see jobs from their own org in QC queue
- MT-17: add Membership.team_ids[], write to it on invitation acceptance and
direct team add/remove; migration backfills from Team.member_user_ids
- MT-19: validate all target_team_ids belong to invitation's org_id at creation
TESTS
- Restore test_cross_tenant_isolation.py (was deleted, only .pyc remained)
- Extend with MT-18 reviewer org isolation tests
QUICK WINS
- W-8: remove time.sleep(1) + dead debug block from POST /jobs (task was
undefined — would have caused NameError → HTTP 500 on every job creation)
- T-13: warn at startup when REDIS_URL configured but connection failed
- T-16: skip language_qc lifespan migration when count=0 (no DB scan on startup)

Subtitles were appearing progressively out of sync (~1.0s early per AD)
because the VTT retimer calculated freeze durations theoretically
rather than using actual rendered segment durations.
Changes:
- video_renderer: Measure actual freeze segment duration after creation
- video_renderer: Return updated placements with actual_freeze_duration
- vtt_retimer: Prefer actual_freeze_duration over calculated values
- render_task: Pass actual durations to VTT retimer
This ensures subtitle timing matches the real video timeline regardless
of any FFmpeg encoding variations.

Add a new "Video Native Mode" translation option that re-processes the
video through Gemini for each target language, generating captions and
audio descriptions directly from visual context. This produces more
natural and culturally appropriate content compared to traditional VTT
text translation.
Changes:
- Add translation_mode field to RequestedOutputs (video_native | traditional)
- Create gemini_ingestion_targeted.md prompt for target language generation
- Add extract_accessibility_targeted() method to Gemini service
- Modify translate_and_synthesize task to handle both translation modes
- Add Translation Mode UI selector in NewJob screen (video_native is default)
- Remove transcreation UI (replaced by video_native mode)
- Remove Google Translate service (replaced by Gemini translation)
- Add LanguageSelector component with searchable dropdown

The VTT retimer had two bugs causing subtitles to display during freeze
periods and become out of sync:
1. Same offset applied to both start and end times (should differ when
pause falls between them)
2. Cues spanning pause points weren't split (causing captions during freeze)
Changes:
- Add _offset_at() for timestamps AT or AFTER pause points
- Add _offset_before() for timestamps STRICTLY BEFORE pause points
- Add _retime_cue() to split cues at pause points into multiple segments
- Add _filter_short_segments() to remove <100ms segments after splitting
- Rewrite retime_for_pause_insert() to use new helper methods
Example fix for cue 8s-12s with pause at 10s (4s freeze):
- Before: 8s-12s (displayed during freeze!)
- After: 8s-10s + 14s-16s (gap during AD)
