Add optional database persistence feature that automatically saves extracted
discrete material plan data to SQL Server. Users can enable this feature in
the settings tab.
Changes:
- Add enable_db_persistence flag to ExtractionConfig (default: disabled)
- Create DiscreteMaterialPlanDAO for database operations with REPLACE pattern
- Update progress tracking to include database persistence stage (90-100%)
- Add database persistence checkbox in settings UI
- Remove verbose logging checkbox from data extraction UI (config-only now)
- Update extraction workflow to save merged DataFrame to database
Progress weights adjusted:
- download: 65% -> 60%
- database: 10% (new stage)
- Other stages adjusted accordingly
