enhance: improve backup reporting and verification for user configs

- Added detailed logging of backup contents (file counts, what was found/missing)
- Enhanced backup info file with configuration summary
- Better visibility into custom thresholds, acknowledgements, and webhook configs
- Improved user feedback about what data was preserved during backup/restore
- Backup already captures all user data correctly (data/, .env, config/)
