feat: implement dynamic Callsign and Radio ID from MQTT General topic

- Node names and IDs are now automatically updated using MMDVMHost/General data
- Added fallback to clients.json values if node is offline or data is missing
- Improved UI with dynamic badge coloring and high-contrast text for IDs
