Preserve verification_prefix in organisation domain deserialisation

[smorimoto]

Summary

• Adds verification_prefix as an optional field to OrganizationDomain and OrganizationDomainResponse interfaces
• Maps verification_prefix → verificationPrefix in deserializeOrganizationDomain

The Events API documentation for organization_domain.* events includes a verification_prefix field in the event data, but the deserialiser was silently dropping it.

Test plan

• TypeScript type check passes (npx tsc --noEmit)
• All existing tests pass (npm test)
• Linter and formatter pass

Greptile Summary

Adds the missing verificationPrefix field to OrganizationDomain interfaces and deserializer. The field was documented in the Events API for organization_domain.* events but was being silently dropped during deserialization.

Changes made:

• Added optional verificationPrefix field to OrganizationDomain interface
• Added optional verification_prefix field to OrganizationDomainResponse interface
• Updated deserializeOrganizationDomain to map verification_prefix → verificationPrefix

The implementation is consistent with existing patterns (matches verificationToken field structure) and correctly handles the snake_case to camelCase transformation.

Confidence Score: 5/5

• This PR is safe to merge with no risk
• The changes are minimal, focused, and follow existing patterns perfectly. The field is correctly typed as optional, properly positioned in the interfaces, and the deserializer mapping is consistent with all other field mappings. No behavioral changes, no breaking changes, and no security concerns.
• No files require special attention
