The UI state about running tasks can be out of sync, especially for
situations where one quickly follows up with a stop, e.g. after
triggering a shutdown by mistake.
So, show the checkbox always for users that got Sys.Modify on (some)
node, but pre-check it still only if there where task detected on
component creation (we could watch the state though and show a hint,
but that's a bit over the top IMO).
Show it also when HA is enabled but explicitly disable it there,
hopefully this increases the chance that the users can understand that
this is done by design, and isn't a bug – ideally we would also show
an extra hint.

Implement a new "guest stop" confirmation message box which first
checks if there is an active shutdown task for the same guest that is
visible to the logged-in user. If there is at least one, the dialog
displays an additional default-on checkbox for overruling active
shutdown tasks. If the user confirms and the checkbox is checked, the
UI sends a guest stop API request with the `overrule-shutdown`
parameter set to 1. If there are no active shutdown tasks, or the
checkbox is unchecked, the UI sends a guest stop API request without
`overrule-shutdown`.
To avoid an additional API request for querying active shutdown tasks,
check the UI's current view of cluster tasks instead, which is fetched
from the `pve-cluster-tasks` store.
As the UI might hold an outdated task list, there are some
opportunities for races, e.g., the UI may miss a new shutdown task or
consider a shutdown task active even though it has already terminated.
These races either result in a surviving shutdown task that the user
still needs to abort manually, or a superfluous `override-shutdown=1`
parameter that does not actually abort any tasks. Since "stop
overrules shutdown" is merely a convenience feature, both outcomes
seem bearable.
The confirmation message box is now always marked as dangerous (with a
warning sign icon), whereas previously it was only marked dangerous if
the stop issued from the guest panel, but not when issued from the
resource tree command menu.
