New and changed:
- Added contact detail views with full saved addresses, edit/send actions, filtered local activity, and explorer History links.
- Added full receive-address display and QR PNG export from the receive view.
- Replaced the History tab with inline recent activity and explorer History access.
- Improved public, shielded, and contact recipient badges across send, shield, and unshield flows.
- Tightened form behavior so value fields reject text input and Enter continues supported flows.
- Fixed extension worker loading under browser extension CSP.
- Fixed auto-lock activity tracking across background worker restarts and preserved connected dApp locked-state profile events.
