Node-RED 4.1.17 (Node 22), fix empty login dialog

- Pin nodered/node-red:4.1.17-22 (was floating 4.1 on Node 20)
- Remove `adminAuth: false` from settings.js: Node-RED checks
  `adminAuth != null`, so false enabled auth with no users and the
  editor showed an empty login dialog. Auth is handled by Authelia.
