Fix deleteing overlay bug on progress tab (#5702)

**Story card:**
[sc-16754](https://app.shortcut.com/simpledotorg/story/16754/delete-overlay-persists-in-the-progress-tab)

## Because

On the progress tab, the 'deleting action' overlay is showing by
default.
This overlay should never be shown on the progress tab, it's a dashboard
action.

/>

## This addresses

- Base state 'display: none;'
- On delete action, add `d-flex` (display: flex;) to show element.

## Test instructions

- Branch `dr-rai-deleting-overlay-progress-tab-fix`
- Add any action to the current quarter action plan.
- Navigate to the progress tab
- The deleteing overlay should not be visible.
