unbanned is true only when this request changed something:

If the user wasn’t banned, you get their username and unbanned: false.
If no account matches, you get user: null and unbanned: false. This is not an error.

An unban removes the banned role and records an entry in the audit log. Nothing is broadcast.

Requires manage_users. It is blocked while you are timed out.

`val`	When
`Unable to save users`	The server could not write the change to storage.
Validation message	`user` is missing, not a string, or blank.
