Ruben Fiszel 372023e995 feat: add ws_base_url instance setting for WebSocket URL override (#8405)
* feat: add ws_base_url instance setting to override WebSocket base URL

Allow deployments behind reverse proxies to route WebSocket traffic
(LSP, debugger, multiplayer) to a different host/port than the main
frontend via a new instance setting.

* feat: move ws_base_url to Advanced section with toggle and connectivity test

- Move setting from Core to Advanced > WebSocket section
- Render as toggle "Custom websocket base url from frontend to
  multiplayer/lsp/debugger" with conditional URL text field
- Add Test connectivity button (always visible) that checks HTTP health
  and WebSocket ping for all three services (LSP, Multiplayer, Debugger)
- Add /ws/ping and /ws/health endpoints to LSP service
- Add /ws_mp/health HTTP and __ping__ WS handlers to multiplayer service
- Add /ping WS handler to debugger service
- Add CORS headers to health endpoints for cross-origin testing

* fix: toggle enabled check and testWs promise resolution

- Fix enabled derived to check only for null (not empty string),
  otherwise the toggle never turns on since toggleEnabled sets ''
- Fix testWs onclose handler to resolve(false) so the promise
  doesn't hang if the server closes without sending a message

* fix: make connectivity test work with existing services

- HTTP test: accept plain text "ok"/"okay" (old services) in addition
  to JSON {"status": "ok"} (new services), reject HTML (SPA fallback)
- WS test: resolve on onopen (connection established) instead of
  waiting for a specific pong message, so the test works even with
  services that don't have the new /ping handler yet
