- Add comprehensive test suite for excluded_category_ids
- 9 tests covering: single category, recursive subcategories,
parent exclusion, direct product override, unrelated categories,
empty blacklist, multiple exclusions, combined blacklists,
available_products_count validation
- Update UI to show excluded_category_ids in 'Productos Excluidos'
- Bump version to 18.0.1.6.0
- Update CHANGELOG with category blacklist documentation
Technical notes:
- Category blacklist was already implemented in model/logic
- This commit adds missing tests and documentation
- Recursive exclusion via get_all_excluded_descendants()
- Blacklist has absolute priority over all inclusion sources
