feat(views): skip owner views, 30-minute device dedupe

- Insert is skipped entirely when the authenticated viewer owns the
  video. Owners re-watching, previewing an edit, or impersonating no
  longer inflate their own view counts.
- Dedupe window drops 1h -> 30min for both auth and guest paths.
- Auth-path dedupe now also matches on device fingerprint / device_id
  cookie, so signing out and back in during the same session doesn't
  double-count a single viewer.
