Resolve chat attachments

POST /users/me/chat-sessions/attachments finds Leni AI file anchors in chat.message_response.summary, collects data-file-id values (HTML attributes, JSON-like strings, and structured summary arrays), then calls Leni POST /resolve-file-url for each id. Successful resolutions return presigned http(s) URLs; otherwise the original file id string is returned for that slot.
