refactor: rename RunBOMExtraction to BOMExtraction for consistency

Rename the main BOM extraction function from RunBOMExtraction to BOMExtraction
to follow consistent naming conventions across the codebase.

Changes:
- M09_BOMExtractor.bas: Rename function RunBOMExtraction → BOMExtraction
- M01_Main.bas: Update function call to use new name
- Update all internal return statements and logger references
