feat(phase-34): add 10 Phase 34 client methods to api.js

Forensic endpoints:
Api.forensicsCircularOwnership(maxLen)
Api.forensicsGhostCompanies(minScore)
Api.forensicsShadowDirectors(minCount)
Api.forensicsBenfords(entityId)

Self-learning endpoints:
Api.selfLearningPatterns()
Api.selfLearningWeights()
Api.selfLearningAudit()

Case memory endpoints:
Api.caseMemoryStats()
Api.caseMemorySimilar(findingTypes)
