[HOLD for payment 2024-07-22] [Unapprove in NewDot - Collect] Show Unapprove btn, add Confirm modal, call API endpoint

[Beamanator]

Tracking issue: https://github.com/Expensify/Expensify/issues/384891

Note: This issue can't be MERGED until https://github.com/Expensify/Expensify/issues/406171 is finished. But it can be started while that other issue is WIP 🙏

Design doc sections:

1. Show “Unapprove” button in NewDot
2. Add new use of component ConfirmModal
3. Create function unapproveExpenseReport in NewDot

Goals:

1. Show the Unapprove button to the correct people at the correct time in the correct place
2. When user clicks the button, show new ConfirmModal IFF report has been exported to connected accounting
   package
   • Note: I probably need to add more details about when this needs to get shown
3. Call new API endpoint, UnapproveExpenseReport
   • Unapproving is Offline Pattern B

Note: For the "show warning modal if report has already been exported to accounting package" stuff, don't implement that here! That will be covered in #44884
