Process-level uncaughtException/unhandledRejection handlers plus
try/catch around upgrade and connection handlers. This will log
whatever is crashing the server on browser WebSocket connections
before the process dies, instead of silently restarting.

WsAdapter registered its upgrade handler first and destroyed sockets
for non-matching paths. Now we remove all existing upgrade listeners,
install ours first, and forward non-terminal/sftp upgrades to the
original WsAdapter handlers for RDP.

The NestJS WsAdapter silently swallowed WebSocket connections through
NPM despite 101 responses in the access log. Replaced with manual
ws.Server instances using noServer mode and explicit HTTP upgrade
event handling. Gateways are now plain @Injectable services, not
@WebSocketGateway decorators.

handleConnection never fires despite browser getting open event.
Adding server-level upgrade listener to see if upgrades reach NestJS.
