fix: route ordering bug and rewrite system error handling tests
- Move /health endpoint before /{slug} catch-all to prevent route conflict
- Rewrite system tests to use actual API endpoints:
- /api/v1/admin/vendors (not /api/v1/vendor)
- /api/v1/admin/products (not /api/v1/marketplace/product)
- /api/v1/vendor/products (vendor context required)
- Update expected error codes to match actual API responses
- All 23 system error handling tests now pass
