test(8.0): use valid camelCase VerbType values in test-factory
createRelateParams / createTestRelation / createKnowledgeGraphTestData cast
PascalCase strings ('RelatedTo', 'DependsOn', 'Contains') `as VerbType` — the
cast hid the mismatch from TS, but 8.0's verb-type validation rejects them at
runtime ("invalid VerbType"). Corrected to the real enum values (relatedTo,
dependsOn, contains), matching the already-correct social-network helpers.
Unblocks find-unified-integration setup (59 failing → 40 passing).
