feat: SAT sync improvements and documentation

- Add custom date range support for SAT synchronization
- Fix UUID cast in SQL queries for sat_sync_job_id
- Fix processInitialSync to respect custom dateFrom/dateTo parameters
- Add date picker UI for custom period sync
- Add comprehensive documentation for SAT sync implementation
