feat(front-hall): wire quick links to Core API dashboard endpoint

Update quick links integration to use new /dashboard/quick-links API:
- Change API path from /front-hall/quick-links to /dashboard/quick-links
- Update field mappings: name→title, icon_name→icon, sort_order→position, is_active→is_visible
- Change ID type from String to int with conversion in provider
- Parse new response format {"links": [...], "total": N}
- Update reorder endpoint from PUT to POST with link_ids
