feat(dirt): integrate assign tasks view into dialog

Implement logic to embed AssignTasksViewComponent within dialog and
handle communication via event bindings.

- Update onMarkAsCritical to check for tasks before closing dialog
- Add checkForTasksToAssign() method using SecurityTasksApiService
- Conditionally transition to AssignTasks view when tasks are available
- Add onTasksAssigned() handler to close dialog after successful assignment
- Add onBack() handler to navigate back to SelectApplications view
- Add loading state guard to prevent double-click on Mark as Critical button
- Only show success toast and close dialog if no tasks to assign
