feat(frontend): update navigation links and expand search coverage

- Hide 'Specification Examples' and 'API Docs' from sidebar documents group, pointing 'Use Docs' externally to pages.dev.
- Complete searchData array to cover all console business pages and missing admin-only pages.
- Add changelog records for these adjustments.
