Subject: [PATCH] feat: autostart Syncthing on WiFi connect

Add a "Start automatically on WiFi" toggle in the Syncthing menu.
When enabled, Syncthing starts automatically when a NetworkConnected
event fires and stops on NetworkDisconnecting.

Toggling the setting on while WiFi is already connected starts
Syncthing immediately. The setting persists via G_reader_settings.
