## Description

When scanning FurAffinity user galleries, favorites, or browse pages, check if the thumbnail URL changes when a submission is re-observed to detect if posts need to be force re-scanned due to content changes. Example: https://refurrer.com/posts/fa@60206635

## Acceptance Criteria

- [ ] System detects when thumbnail URLs change during scanning
- [ ] A new PostFile is created rather than overwriting the URL and blob of the original PostFile
- [ ] Changed submissions are flagged for re-scanning
- [ ] Re-scanning is automatically triggered for flagged posts
- [ ] System tracks thumbnail URL changes over time
- [ ] False positives are minimized through proper comparison logic
