Fix variant tests to match CDA API response structure

Correct variant_uid location in API response:
- variant_uid is inside each publish_details array element
- Not as a separate 'variants' key at top level

Verified against:
- Official CDA API documentation
- Actual stack export data showing variant_uid in publish_details
- User confirmation of published variant entries

Tests now properly validate:
- Variant UID presence in publish_details array
- Correct variant UID matches requested one
- SDK .variants() method functionality

4 tests fixed: test_23-26 variant tests
