Gift cross-device sync, snapshot size cap, reliable SW updates, gift-detail layout

- Gifts now sync across devices: gift records + reserved/reclaimed coin
  sets ride the encrypted snapshot as a merge-safe extension (like ark),
  and every gift state change (create/reclaim/revoke) triggers a
  saveCache so it actually publishes. A gift made on one device now
  shows on the others.
- Cap the published snapshot at ~40KB JSON (relay rejects >64KB events,
  nip44 expands ~1.5x): trim oldest on-chain txs when oversized; another
  device backfills via rescan. Typical wallets untouched.
- Service worker: register with updateViaCache:'none' so a new build is
  detected immediately (not held by the 4h HTTP cache), and reload once
  on controllerchange so the fresh app runs without a manual second
  refresh.
- Gift detail: View/Reclaim share a row, Revoke on its own full-width
  line so 'Revoke now' stops wrapping.
