fix:(dashboard) pending difference rounding on order details page (#11336)

**Why**
- if pending difference is lass then the rounding threshold for currency the page would show for example "Refund -0.00$"

**What**
- example: hide the refund button if the pending difference in USD is -0.004
- example: show refund button if pending difference on USD is -0.007
