Delete a comment

Deletes the comment from its network, as the account, with the replies under it, and from the thread: it no longer shows in Get a thread. When it is the thread's first comment (first), the thread goes too, and leaves every list and count. One already gone from the network counts as deleted, so a delete that failed can be asked again. Errors: 400, before any call, when it is not a comment (a message) or its network does not allow it for this comment, with why (moderationProblem); 422 capability_missing when the account's login does not allow managing comments (on Threads, until Meta approves Rizamo's access to replies); 409 when the account needs a new login or is not active, the reply is still sending, or the network refused, with its reason; 404 for a thread or comment the caller does not reach. On Threads, 422 too for the profile's own reply until Meta approves Rizamo's access to deletes.
