Support for multi-session PSC flow on hosted KYB for Business

To support verification of multiple PSCs on hosted KYC/KYB for Business-type users:

• New ApiIdentityVerifications.RetryPscAsync(identityVerificationId, pscId, psc) method, calling PUT /identity-verifications/{IdentityVerificationId}/pscs/{PscId}/retry. The PscRetryPutDTO payload is optional and may carry FirstName, LastName, Email, DateOfBirth
• New PscDTO (with PscDataDTO for its Data entries) and a PSCs list on IdentityVerificationDTO

See the multi-session PSC flow guide and the API release note for more details.

Identity verification event types

New event types: IDENTITY_VERIFICATION_PSC_PENDING, IDENTITY_VERIFICATION_PSC_VALIDATED, IDENTITY_VERIFICATION_PSC_FAILED, IDENTITY_VERIFICATION_PSC_ABANDONED, IDENTITY_VERIFICATION_PENDING_PSC_ACTION, IDENTITY_VERIFICATION_EXPIRED

Echo – GET List Intent external providers

• New ApiPayIns.GetExternalProvidersListAsync() method, calling GET /payins/intents/external-providers, returning the provider names as a List<string>

Echo – Tag on intents and splits

• Added Tag to PayInIntentCapture, PayInIntentRefund, PayInIntentDispute, and PayInIntentSplitPutDTO

Idempotency error details for failed calls

• IdempotencyResponseDTO now exposes a ResponseException property, populated when the original call returned a non-2xx status. It is null when the original call succeeded, and Resource keeps its previous content
