Check Fansly attachments for 4K variants and upgrade if available.

This script:
1. Finds all non-4K video attachments from Fansly Direct
2. Re-fetches media info from the Fansly API
3. Checks if a higher resolution variant is available
4. Updates the attachment URL and resets for re-download if upgrade found
