Improve blocked-off dates list UI clarity

When viewing the list of blocked-off dates, add a subtle visual cue so each row feels clearly connected to its action icons (duplicate and delete).

Possible approaches:

  • Add a light 1px bottom border (#dee2e6, consistent with the section above) to each row to separate entries more clearly.

  • Optionally introduce a soft hover state that lightly highlights the full row to make its boundaries more obvious.

Why:
With multiple rows visible, it’s easy to lose track of which date/time relates to which action icons. Small visual cues like these improve readability and reduce the risk of misclicks, particularly in longer lists.

Acceptance criteria:

  • Each blocked-off date row has a clear divider or visible hover state.

  • The hover state highlights the entire row without affecting text readability.

  • Any connector line remains subtle and does not add visual clutter.

  • No layout changes or structural impact. Styling must meet accessible contrast standards.
