feat: implement site logins, queues parity, and engine settings updates

- Implemented Site Logins parity by integrating auth credentials to Rust backend (Aria2 and yt-dlp) and fetching metadata.
- Implemented Queues functionality including context menu actions (start, pause, rename, delete).
- Updated Engine settings UI to include Deno and render clean version output without extra trademark info.
