[Afterwork] Basic - Edit my post/comment/reply

[nicobao]

Figma & Flow

The "..." in there:

TODO: explain what comes next.

Logic

Generate the same anonymous pseudonym and then send the editing message.

In backend, we create a "linear linked list of edition".
In the protocol, reply == reply to one of the element of this list (== to its UID), with the "root" UID reminded in the proof. So we can track to which data a specific message was sent to, avoiding users to change their message COMPLETELY after other users liked/replied. Edit should only be used for fixing small things.
