feat: enhance incomplete Vorgaben page with table layout and admin integration

- Redesign incomplete Vorgaben page from card layout to unified table format
- Add visual status indicators (✓/✗) for each completeness category
- Link Vorgaben directly to admin edit pages (/autorenumgebung/ instead of /admin/)
- Enhance Vorgabe admin with Kurztext and Langtext inlines for complete editing
- Update all tests to work with new table structure and admin URLs
- Add JavaScript for dynamic summary count updates
- Maintain staff-only access control and responsive design

All 112 tests passing successfully.
