Add transport raid functionality to Falukant daemon: Introduced falukant_transport_raid module with SQL queries for managing transport raids, including candidate transports and user reputation updates. Updated documentation to reflect new WebSocket events and integrated the module into the UndergroundWorker for seamless processing of transport-related events.
