## Summary by cubic
Made edit and delete always visible on custom provider cards and
restructured the card layout for clearer actions and status. Improves
discoverability and aligns with #1358.

- **Refactors**
- Replaced popover menu with visible Edit and Delete icon buttons
(data-testid: edit-custom-provider, delete-custom-provider).
- Moved status badge and actions to the top; title now sits below;
badges don’t wrap.
- Updated e2e tests to use new buttons and adjusted selectors for the
updated heading.
