refactor(gui): ✨ update album download options and improve session validation

* Added a new action to download all albums in a playlist.
* Removed the deprecated `validate_session` method and replaced it with a direct call to `self.tidal.session.check_login()`.
* Adjusted the UI layout in `dialog_settings` to accommodate new options and improved sizing.
