You can set the padding property in last-system-spacing (or
first-system-spacing or first-system-nontitle-spacing). I've just
increased them all to 1 by default, but feel free to modify the default
if you want it larger.

There's currently a bug in that anything living in the Score context
(bar numbers, rehearsal marks, etc) isn't counted in the layout problem.
I'm currently testing a patch for this.

Regarding your "Top" context: why do you override VerticalAxisGroup
#'Y-extent = ##f? This is likely to confuse the layout algorithm even
after the bug I mentioned is fixed.
