debug: add [BOOKMARK_TS] logging to investigate timestamp issues

- Log parentCreatedAt value when processApplesauceBookmarks is called
- Log each bookmark event with its kind and created_at timestamp
- Log count and timestamp for notes, articles, and URLs being processed
- Prefixed with [BOOKMARK_TS] for easy console filtering
