Add comprehensive coverage tests for database inventory and scan rules

- Introduced `database_inventory_coverage_tests.cpp` to validate project inventory repository functionality, including error handling for invalid project IDs and missing payload keys.
- Implemented tests for persisting and pruning files, autoloads, classes, and unknown entries in the project inventory.
- Added `scan_rules_coverage_tests.cpp` to cover various scenarios for scan rules, including classification, hint detection, and dirty state detection.
- Enhanced existing functionality with additional checks for file types, extensions, and type hints.
- Updated binary object files for native scan rules and script parser.
