fix(tracker): make the objective marker button usable at larger sizes

The button shared the quest gutter with the collapse button, the quest
item buttons and the zone header text, so anything past the default size
was clipped by the tracker edge or drawn on top of its neighbours.

Give it a gutter of its own instead. GetSuperTrackMarginReserve feeds
questMarginLeft, which every layout and width calculation already builds
on, and the quest item buttons and zone labels are shifted by the same
amount. The button then anchors flush left of the line and the tracker
widens to match, so nothing overlaps at any size. Raise the size cap to
70 now that it fits, and drop the hover tooltip.

Also stop relying on the SetSuperTrackedQuestID hook as the only source
of truth. It never fires while the player is a ghost -- the corpse arrow
takes over the marker -- and it has not fired yet on a login or reload,
which left the tracker with no idea what was tracked in both cases. The
client is now asked directly: the watch frame POI buttons flag their own
selection, the map pins say it through their art (the selected variant
sits half a texture above the normal one), and the quest log selection
answers for the login window when no pin is styled yet. Selection calls
are hooked for the same reason, so clicks repaint while dead, and the
requests are coalesced because callers select a quest log entry and
restore the previous one a line later.
