refactor: optimize material deletion with exact code matching and database queries

- Change from fuzzy material name matching to exact material code matching
- Migrate from MaterialsTypeToBeDeleted to MaterialsToBeDeleted table
- Add should_delete_material() for on-demand database queries
- Remove in-memory material list loading to reduce memory footprint
- Update documentation to reflect new matching logic
- Remove main scripts from git tracking (contain user-specific config)
