Hydrate payload.teeth into the PLAN chart ONLY (status is left
untouched), mirroring the per-tooth hydrate importStatus() performs for
the status chart. Marks the plan chart initialized. Repaints the DOM only
when PLAN is the currently active chart mode — hydrating a chart that
isn't on screen must not visibly disturb whatever IS on screen (mirrors
setChartMode()'s own full-repaint-on-activation behavior).
