fix: resolve runtime errors for NestJS, Kong, and voice-service

- Dockerfile.service: fix entry point path (dist/services/{name}/src/main)
  due to tsconfig paths widening rootDir during compilation
- Kong config: remove unsupported ws/wss protocols (WebSocket works
  automatically over http/https in Kong 3.7)
- voice-service: fix pipecat import path for v0.0.30 API
  (pipecat.transports.network.websocket_server with lowercase class names)
- voice-service: add openai dependency required by pipecat anthropic service
