[Additive] OpenAI: Value restriction lifted

OpenAI's published API specification now accepts additional values for the VectorStoreExpirationAfter object's anchor field, removing the previously documented value list that restricted it to "last_active_at". The change affects code sending VectorStoreExpirationAfter objects across 4 OpenAI operations, and existing requests continue to work. The update is a relaxation of the schema rather than a breaking change, according to the specification-based report.
