DateTimeline now skips section rank 0 (intake) and renders stage lanes
top-to-bottom 5→1, matching how the framework actually numbers stages.
MembershipChart's latest-Actual label was placed at the circle's
x + 6, which overflowed the SVG when the most-recent point landed near
the right padding. Anchor it to xOf(maxT) - 4 with textAnchor="end",
mirroring the Goal label so both endpoint labels stay inside the chart.
