Fix(1-3553): fix focus styles and tab navigation for segments + constraints (#9655)

Fixes a few small focus styling and tab navigation issues for the new
segments + constraints.

Before:
The segment acc header was tabbable even though you can't do anything
with it (by mouse or by keyboard)

The focus color would stay even when you're focusing stuff inside the
accordion

Constraint items have focus styles that exceed the accordion borders,
causing a weird squaring effect:

After:
The segment acc header isn't reachable by tab anymore.

The segment acc header doesn't change its background color on elements
inside getting focus:

The constraint item has rounded corners for focus styles too:
