refactor: extract helpers for verify print, scan loop, and per-contact export

Browse Source 
- extract _show_integrity_issues() from cmd_history verify block
- extract _ff_scan_lines() shared by _ff_state_build and _ff_state_extend
- extract _export_one_contact() from log_database_export_to_flatfile loop
