docs: Add conversation_list_item schema for list/search endpoints

Add a new `conversation_list_item` schema (without `conversation_parts`)
for list/search endpoints, keeping the original `conversation` schema
completely unchanged. This ensures `GET /conversations/{id}` is not
affected while list/search responses no longer misleadingly document
`conversation_parts`.

Addresses internal ticket 215473350697203.
