I'll build this tenant management user list page with the certification badge filter. Let me first check the existing project structure and components.

Now I have all the context I need. Let me create the tenant management user list page with the filter sidebar. I'll build the components:

I've built the tenant management user list page with the certification badge filter as specified. The implementation includes:

1. TenantSidebar - Left navigation with organization management menu items, with "ユーザー" highlighted as active

2. FilterSidebar - Right slide-in sheet (600px width) with:

   • ユーザー名 (username) input field
   • 認定バッジ (certification badge) - NEW single-select dropdown with the 5 sample options
   • 組織レビュアー / 人事レビュアー - shown only on the "契約中" tab
3. FilterButton - Shows active filter count badge
4. Tabs - "契約中" and "契約終了" tabs with proper filtering
5. UserTable - Displays user data with all specified columns
6. Pagination - Basic pagination controls

The filter logic properly combines all conditions with AND, updates URL parameters including certificationId, and resets to page 1 on search. Dark mode is fully supported with the specified color scheme.
