feat(render): 5 quality tiers (360p–4K) + ETA on render page; 24h session

- Render page: resolution picker now 360p/540p/720p/1080p/4K; live ETA
  ('تقریباً … باقی مانده') computed from progress rate; preview+progress bar already wired.
- render-schemas: resolution enum + RESOLUTION_DIMENSIONS add 360p/540p.
- render-jobs.mapQuality: 5-tier → render_quality (Low/Medium/High/Full).
- Session: Jwt__AccessTokenMinutes=1440 (24h) via compose so logins persist
  (refresh middleware + 30d refresh token back it up).

(Real per-tier output height still pending: render-svc r_height is hardcoded 1080 →
node ffmpeg scale — next.)
