fix: fix hidden bookmark detection by using applesauce's built-in logic

- Remove custom isEncryptedContent function that was too restrictive
- Use applesauce's hasHiddenContent() and hasHiddenTags() functions instead
- These properly detect encrypted content regardless of format
- Remove failing relay.snort.social from relay list
- Add detailed logging to show hidden content detection status
