fix: right click on request opens far to the right #8181

[iamtimleonard]

This addresses and closes #8181.

The current behavior when right clicking on a request or request group is for the context menu to always open at the far right side of the panel:

This fix allows the context menu to open at the location of the cursor, if needed:

contextMenuPosition catches the location of the user's cursor onContextMenu and passes it down to RequestGroupActionsDropdown or RequestActionsDropdown. setContextMenuPosition also needs to be passed down to those components to reset contextMenuPosition onOpenChange (eg the user instead clicks on the icon to open the dropdown).

The x and y positions are then dynamically applied to the dropdown if needed.

It isn't the prettiest solution but it gets the job done. I wasn't sure how to test this, so let me know if that is a requirement.
