* fix(xray): hot-apply Hysteria client changes without replacing the inbound

diffInboundUsers only allowed per-user AlterInbound ops for vless, vmess
and trojan. For a hysteria inbound every client add/remove/update became
DelInbound + AddInbound: the UDP listener was recreated and all QUIC
sessions of that inbound were lost. quic-go sends no stateless reset, so
every connected client stalled until its idle timeout (30s by default)
after each unrelated client mutation.

XrayAPI.AddUser already builds a hysteria account and Xray-core's
hysteria server implements AddUser/RemoveUser, so adding the protocol to
userDiffableProtocols is sufficient.

* test(xray): say which branch each drop-guard protocol takes

With hysteria in userDiffableProtocols its dropped client reaches the
guard through the per-user diff, so the test named for protocols the
diff cannot handle no longer described its hysteria case.
