Changes:
- Dashboard: add project_manager case (final review / QC counts / new job widgets)
and production case (AI pipeline / failures widgets)
- Sidebar: add project_manager to Final Review and Audit Log nav items;
live badge counts for QC Queue (pending_qc) and Final Review (pending_final_review)
- App.tsx: add project_manager to Final Review and Audit Log RoleGates (W-10, PM-18)
- Login: role-based redirect after login — linguist/reviewer → /qc/queue, others → /
- language_qc._assert_can_approve: enforce two-stage QC; remove linguist self-approve
fallback; require reviewer assignment + submitted_for_review_at (W-6)
- routes_jobs.complete_job: allow project_manager to complete jobs (W-9)
- notify.py: re-enable email notifications (W-7)
- Fix 400 on cue save: treat empty-string audio_description_vtt/captions_vtt as absent
both in backend (truthy check) and frontend (|| undefined) — root cause was adVtt
initialising to '' when job has no AD track
