feat: Allow downloading without being logged in

Removes the strict requirement for a `SESSDATA` cookie, allowing the archiver to proceed even when not authenticated.

- Replaces hard assertions for login status with warnings.
- Informs the user that video quality is limited to 1080p when not logged in.
