disconnectClientTemporarily still gated on the protocol list from before
XrayAPI.AddUser learned hysteria, so an over-limit Hysteria2 client kept
its QUIC session until the fail2ban ban aged out, while a VLESS client in
the same situation was dropped at once. buildUserAccount handles hysteria
and model.Client already marshals the auth field the re-add needs, so admit
the protocol. wireguard stays excluded: its keepAlive marshals as a JSON
number, which the string-only user-field parsing rejects after the user was
already removed.
Closes#6256
