fix: remove decrypt queue that was blocking highlight signing

- The global decrypt queue in bookmarkProcessing was getting stuck
- Caused all NIP-46 operations to hang indefinitely
- Decrypt already has per-call timeouts; queue was unnecessary
- Highlights should now sign immediately without waiting for bookmarks
