Naiyuan Qing 2ed8538018 test(chat): guard attachment survival on empty-chat cancel
Cancelling an empty chat task deletes the user message, and
attachment.chat_message_id is ON DELETE CASCADE (migration 083), so the
detach-before-delete in finalizeCancelledChatMessage is the only thing
keeping the user's attachment from being silently destroyed. Nothing
covered it.

Add a DB regression test that binds an attachment to the cancelled user
message and asserts: the row survives the cascade (chat_message_id NULL,
chat_session_id retained), the cancel response returns it via
cancelled_chat_message.attachments, and a resend re-binds it to the new
message. Verified red when the detach step is removed.
