Mason Daugherty 8042b04da6 fix(anthropic): clean up null file_id fields in citations during message formatting (#32592)
When citations are returned from streaming, they include a `file_id:
null` field in their `content_block_location` structure.

When these citations are passed back to the API in subsequent messages,
the API rejects them with "Extra inputs are not permitted" for the
`file_id` field.
