feat(notifications): integrate daily notification plugin into AccountViewView

- Add notification methods to PlatformService interface
- Implement notification support in CapacitorPlatformService with plugin integration
- Add stub implementations in WebPlatformService and ElectronPlatformService
- Add nativeNotificationTime, nativeNotificationTitle, and nativeNotificationMessage fields to Settings interface
- Create DailyNotificationSection component for AccountViewView integration
- Add Android manifest permissions (POST_NOTIFICATIONS, SCHEDULE_EXACT_ALARM, RECEIVE_BOOT_COMPLETED)
- Register daily-notification-plugin in capacitor.plugins.json
- Integrate DailyNotificationSection into AccountViewView

Features:
- Platform capability detection (hides on unsupported platforms)
- Permission request flow with fallback to settings
- Schedule/cancel notifications
- Time editing with HTML5 time input
- Settings persistence
- Plugin state synchronization on app load

NOTE: Currently storing notification schedule in SQLite database, but plugin
was designed to store schedule internally. Consider migrating to plugin's
internal storage to avoid database initialization issues.
