refactor(ui): invoke the stable update directly

Remove the dedicated stable-update wrapper and invoke the Tauri WinGet command directly from the official release notification. Non-Tauri and remote windows retain the existing release link behavior through the toast fallback.

Validated with the UI TypeScript check and Cargo check.
