Add SEO data generation and testing for bilingual pages

- Implemented SEO data structures for programmatic tool and collection pages.
- Created functions to build FAQs and content sections for SEO pages.
- Added tests to ensure at least 50 bilingual SEO pages are generated, no duplicate English slugs, and matching Arabic localized paths.
- Verified that both tool and collection SEO inventories are populated adequately.
