feat: add database-driven material validation with multi-mode support

This commit enhances the material validation functionality to support
database-driven workflows alongside the existing Excel-based approach.

## New Features

### DAO Layer
- Add ProductionContractDataDAO for querying production contract data
- Add MaterialsToBeDeletedDAO with full CRUD operations
- Enhance DiscreteMaterialPlanDAO with query_all(), query_by_source_numbers(),
  and get_unique_material_names() methods

### Validation Modes
Support for 4 validation modes in MaterialValidationTab:
1. Database Full - Query all materials from DiscreteMaterialPlanData
2. Database Filtered - Query by ProductionID.txt file
3. Excel Existing - Validate from existing Excel file
4. Excel Full - Complete workflow with ERP extraction

### Configuration
- Add ValidationConfig dataclass with data_source, batch_size, match_mode,
  enable_crud_operations, and default_manager fields
- Update ConfigLoader to support validation configuration
- Add validation settings section in SettingsTab GUI

### Query Chain
Implementation of full query chain:
ProductionID.txt (总排号) → productionContractData (生产订单号) →
DiscreteMaterialPlanData (SourceNumber) → MaterialName →
MaterialsToBeDeleted comparison

## Backward Compatibility
All existing Excel-based validation methods remain unchanged, ensuring
no breaking changes for existing workflows.
