This PR implements a global WebSocket broadcast whenever a callsign lookup occurs in the QSO window. It enables external hardware and software (rotators, external displays, and integrators) to react instantly to the station being logged.
Key changes:
- Added 'broadcastLookupResult' to assets/js/cat.js.
- Implemented automatic WebSocket initialization if a local CAT-URL (127.0.0.1/localhost) is detected.
- Triggered broadcast from assets/js/sections/qso.js upon successful lookup, including full metadata (Azimuth, LoTW status, US County, Slot confirmation, etc.).
