feat: implement material validation UI in CleanerPage

New Features:
- Material validation from database (full table or filtered by ProductionID)
- Checkbox selection for materials to delete with auto-select for marked items
- Manager-based filtering (Admin only)
- Two-phase deletion: confirm (mark in DB) + execute (delete from ERP)
- Export results to CSV
- Hide/show checked items feature (User mode)
- Share Production IDs between ExtractorPage and CleanerPage
- Persist page state using sessionStorage

Bug Fixes:
- Fix MySQL query rowCount for INSERT/UPDATE/DELETE operations
- Add AUTO_INCREMENT to MaterialsToBeDeleted.ID (preserved 43 records)
- Add UNIQUE constraint on MaterialsToBeDeleted.MaterialCode

Files Added:
- src/main/ipc/validation-handler.ts
- src/main/types/validation.types.ts
- src/main/services/database/materials-to-be-deleted-dao.ts
- src/main/services/database/discrete-material-plan-dao.ts

Files Modified:

- src/renderer/src/pages/ExtractorPage.tsx
- src/renderer/src/App.tsx (add navigation tabs)
- src/main/services/database/mysql.ts
