…REST API

### What is this PR for?
Currently, configuration data is fetched through both REST API and WebSocket channels. However, the WebSocket path does not perform permission checks, and the only required data from it is the WebSocket max message size. 

I extracted the websocket max message size field into a dedicated REST API, to improve security and simplify configuration handling.
