feat: Add auto-sync, fix partner linking UI, update sharing settings

- Add 10-second periodic auto-sync to CycleEntriesNotifier
- Fix husband_devotional_screen: use partnerId for isConnected check, navigate to SharingSettingsScreen instead of legacy mock dialog
- Remove obsolete _showConnectDialog method and mock data import
- Update husband_settings_screen: show 'Partner Settings' with linked partner name when connected
- Add SharingSettingsScreen: Pad Supplies toggle (disabled when pad tracking off), Intimacy always enabled
- Add CORS OPTIONS handler to backend server
- Add _ensureServerRegistration for reliable partner linking
- Add copy button to Invite Partner dialog
- Dynamic base URL for web (uses window.location.hostname)
