Pull request overview

This PR adds network selection functionality to the system tray menu, enabling users to switch networks directly from the tray without opening the web UI. The implementation includes a callback mechanism to synchronize network changes between the systray and web interface, with the web UI polling every 2 seconds to detect changes.

Key changes:

• Added network change callback system in the config manager to notify the systray when networks change
• Implemented a dynamic network submenu in the systray with checkmarks showing the active network
• Enhanced the web UI to poll the network endpoint every 2 seconds to detect systray-initiated changes
