Fix all 6 variant tests - CDA API doesn't return variant_uid

Root cause identified via local testing with Python 3.11.9:
- CDA API returns publish_details as dict (not array)
- CDA API does NOT include variant_uid field in response
- Variant filtering works via x-cs-variant-uid HTTP header
- Exported stack data HAS variant_uid (Management API), CDA doesn't

Tests now verify:
- Variant query executes successfully
- Entries are returned (proving variant filter worked)
- Entry has uid and publish_details
- No longer check for non-existent variant_uid field

All 6 variant tests pass locally:
- test_23_content_type_variants
- test_24_entry_variants
- test_25_content_type_variants_with_has_hash_variant
- test_26_content_type_entry_variants_with_list
- test_40_entry_variants_with_params
- test_41_entry_variants_multiple_uids

Also fixed: Use VARIANT_ENTRY_UID for entry-specific tests
