@* Create/edit modal for an equipment-bound scripted alarm, wired straight into IUnsTreeService. The host
|
||||
page owns visibility and supplies the owning equipment id (create) or the loaded ScriptedAlarmEditDto
|
||||
(edit), plus the candidate predicate-script list. The owning equipment is fixed by the tab, so there is
|
||||
no equipment selector. On a successful save it raises OnSaved so the host can refresh the equipment's
|
||||
alarms in place. Lifted from the standalone ScriptedAlarmEdit page (retired in a later task). *@
