Fix toggling all checkboxes of failed imports:

- Rename classes and function to something more descriptive.
- Listen to the element checked status instead of a click on a non‑focusable element.
- Use specific DOM targets instead of relying on the DOM ancestor tree.
- Add a skip‑link to the end of the list and avoid tabbing through all failed items.
- Update related i18n strings in French.
- Avoid having the label on the whole width to prevent accidental click.
- Move `fieldset` out of `ul`.
