Add delete option to reauth cards on integrations dashboard (#28020)

* Add delete option to reauth cards on integrations dashboard

Users can now delete config entries directly from the reauth card that appears at the top of the integrations dashboard, instead of having to scroll down to find the original integration card.

The delete option:
- Appears in the three-dot menu on reauth cards
- Shows a confirmation dialog before deletion
- Handles application credentials cleanup
- Shows restart notifications when required
- Uses the same styling and localization as the integration entry delete
