fix: Fix 3 critical bugs - voice tracking, session persistence, and status updates

BUG-1: Voice tracking not saving activities
- Fix activity data format to match backend CreateActivityDto
- Change 'timestamp' to 'startedAt' and 'data' to 'metadata'
- Remove duplicate voice button from mobile TabBar

BUG-2: Session persistence after revocation
- Add logout() call when revoking all sessions
- Add logout() call when removing all devices
- Ensures user is logged out after session/device revocation
- Clears tokens and redirects to login

BUG-3: Voice modal status not updating
- Set identifiedActivity before saving to show tracker name
- Display "Adding to [tracker] tracker..." during save
- Improves UX by showing which tracker is being updated
