Add server-side folder filtering using IMAP LIST patterns and enhance
message filtering to use IMAP SEARCH with keyword filters when available.
Key improvements:
- Add list_filtered_mailboxes() method using IMAP LIST with patterns
- Use server-side filtering instead of client-side folder filtering
- Enhance message search to use IMAP SEARCH for subject/sender keywords
- Add has_keyword_filters() method to MessageFilter
- Reduce network traffic by leveraging IMAP server capabilities
- Remove dependency on client-side filter_folders function
This achieves full feature parity with the updated Go implementation
and ensures both versions use IMAP standards optimally.
