🐛 Bind MCP PluginBridge WebSocket to configured host

The plugin WebSocket bridge ignored PENPOT_MCP_SERVER_HOST and bound all interfaces, exposing unauthenticated task dispatch to the network in single-user mode. Pass mcpServer.host into WebSocketServer, mirroring the ReplServer fix, so the bridge binds localhost by default and 0.0.0.0 only on explicit opt-in. Closes #11603.
