fix: Add notification channel creation and improve native fetcher configuration

- Add notification channel creation in TimeSafariApplication for Android 8.0+
  Required for daily notifications to display properly. Channel ID matches
  plugin's 'timesafari.daily' channel.

- Convert localhost to 10.0.2.2 in CapacitorPlatformService for Android emulators
  Android emulators cannot reach localhost - they need 10.0.2.2 to access
  the host machine's API server.

- Refresh native fetcher configuration when API server changes in AccountViewView
  Ensures background notification prefetch uses the updated endpoint when
  user changes API server URL in settings.

- Add directive for fixing notification dismiss cancellation in plugin
  Documents the fix needed in plugin source to cancel notification from
  NotificationManager when dismiss button is clicked.

These changes ensure daily notifications work correctly on Android, including
proper channel setup, emulator network connectivity, and configuration refresh.
