Add flexible IP access control to WebUI config

Replaces the 'disableNonLANAccess' option with a more flexible access control system supporting 'none', 'whitelist', and 'blacklist' modes, along with IP list and X-Forwarded-For support. Updates backend API, config schema, middleware, and frontend UI to allow configuration of access control mode, IP whitelist/blacklist, and X-Forwarded-For handling. Removes legacy LAN-only access logic and updates types accordingly.
