feat: Refactor routing signal types and enhance web API for routing devices

Browse source 
- Renamed `UsbOutput` to `Usb` in `eRoutingSignalType.cs`.
- Removed unused `UsbInput` and `SecondaryAudio` signal types.
- Added new HTTP route for retrieving routing devices and tielines in `EssentialsWebApi.cs`.
- Implemented `GetRoutingDevicesAndTieLinesHandler` to handle requests for routing devices and tielines, including detailed port information.
- Updated `GenericSink` to remove `SecondaryAudio` from input port signal types.
- Created `ICurrentSourcesMessenger` to manage current source information and status updates.
- Introduced `IDeviceInfoProviderMessenger` for device information communication with debounce functionality.
- Updated `MobileControlSystemController` to use new messenger classes for current sources and device info.
- Added console commands for listing tielines and visualizing routes in `ControlSystem.cs`.
- Implemented methods for visualizing routes and current routes, including filtering options.
