Add argo application delete confirmation

[callmevladik]

Currently, the 'Delete' button in the CD stage page removes Argo CD application resources. This task involves adding an additional confirmation form before a user can delete these resources. The confirmation form should include a list of Argo CD applications that will be removed after confirmation.

Implementation Plan

1. Add an additional confirmation form that appears when the 'Delete' button is clicked in the CD stage page.
2. The confirmation form should include a message warning the user about the deletion and require explicit confirmation.
3. Retrieve and display the list of Argo CD applications that will be removed in the confirmation form.
4. Ensure that the deletion proceeds only after the user confirms the action in the confirmation form.
5. Test the implementation to ensure that the confirmation form works as expected and that the list of applications is accurate.
