Updated the relay host for RustDesk server from "mx.surfsite.org" to "rustdesk.hoyer.world". This ensures the service uses the new designated host for signal relay.
Enabled `forceSSL` for the RustDesk nginx configuration to ensure secure connections. Replaced `proxyPass` with detailed `extraConfig` to include necessary headers and support for WebSocket connections.
Moved rustdesk-server settings from `default.nix` to a dedicated module `rustdesk.nix`. This improves configuration structure and ensures better modularity for maintainability.
