style(tracker): tighten the gutter ahead of a quest title

The collapse button moves to 4px from the quest text, the marker to 1px
from the collapse button, and the quest item buttons 6px in from the edge
of the line. Everything ahead of the title is that much closer to it, so
the marker, which tucks in to the left of whichever of those it finds,
hangs less far over the tracker's edge -- at the default sizes it no
longer reaches past it at all when the quest has no item button.

The item button offset lives in TrackerLinePool now: the marker is placed
against it, so the two cannot drift apart.
