bindCloudUI() already wires a click handler on #sunCloudPullV2
(confirm dialog -> pullRemote({replace:true, quiet:false}), which
backs up the local copy and force-replaces it with the server's
orders/clients/etc.), but renderCloudUI()'s template never actually
emitted a button with that id - the handler was permanently a no-op.
Adds the missing button to the "Профиль и аккаунт" settings card.
