fix(admin): prevent edit modal from closing immediately on tap

Fix the card types management edit modal that was closing immediately after opening due to event propagation. Added .stop modifier to all action button tap handlers (edit, toggle, delete) to prevent bubbling to parent modal-mask element.

- Changed @tap="openEdit(ct)" to @tap.stop="openEdit(ct)"
- Changed @tap="toggleActive(ct)" to @tap.stop="toggleActive(ct)"
- Changed @tap="confirmDelete(ct)" to @tap.stop="confirmDelete(ct)"

This fixes the bug where the edit modal would open and close in the same event cycle, making it impossible to edit card types.
