fix: update 61 outdated test mocks to match current schemas

Tests were failing due to stale mock objects after schema extensions:
- DSFA: add _mapping property to _DictRow, use proper mock instead of MagicMock
- Company Profile: add 6 missing fields (project_id, offering_urls, etc.)
- Legal Templates/Policy: update document type count 52→58
- VVT: add 13 missing attributes to activity mock
- Legal Documents: align consent test assertions with production behavior
