Enhance 5G modem management with integrated web GUI and connection control

- Introduced a web GUI for managing 5G connections, replacing the standalone 5g-router service.
- Updated scripts to ensure exclusive access to the AT port, preventing conflicts.
- Improved troubleshooting documentation in 5G_MODEM_TROUBLESHOOTING.md, adding checks for processes using the AT port.
- Enhanced connection management in the web app, including auto-connect and detailed status APIs.
- Updated installation scripts to reflect changes in service management and dependencies.

+If you prefer to run without the Web GUI, you can still use the legacy service:
+
+```bash
+rc-update del 5g-webgui default
+rc-update add 5g-router default
+service 5g-router start
+```

+This runs `connect-5g.sh` without the web interface.
