fix(bs4): Place tooltips to the right in modal header

Problem

Tooltips are rendered by default on top of their OverlayTrigger, and for modal headers the tooltips appear mostly off-screen:

Solution

Adds placement="right" property to OverlayTrigger components that appear in modal headers.
Other OverlayTriggers remain untouched as we don't have the issue mentioned above.

Looks good to me! I think I did something like this locally at one point, but didn't keep it for some reason...
