Investigations API response fields now use snake_case

This changelog entry is added retrospectively.

Investigations API responses now use snake_case field names, matching the underlying schema, instead of camelCase.

Developer impact: Every field name in every Investigations API response has changed casing. For example, investigationId is now returned as investigation_id. Integrations that read fields by their previous camelCase names will no longer find them.

Action required: Update your integration to read Investigations API response fields in snake_case (for example, investigation_id instead of investigationId).
