Problem:
- GET /api/v1/admin/code-quality/stats returned 500 error
- Pydantic validation error: "last_scan Field required"
- When no scan data exists, service returned dict without last_scan field
- DashboardStatsResponse model required last_scan field
Solution:
1. Added last_scan: None to empty state return dictionary
2. Made last_scan field explicitly optional with default value (= None)
3. Ensures field is always present in response
Changes:
- app/services/code_quality_service.py: Added "last_scan": None
- app/api/v1/admin/code_quality.py: Changed to last_scan: str | None = None
This fixes the 500 error when accessing /admin/code-quality page
with no architecture scan data in the database.
