The public tree chart was fixed at 3 ancestors / 2 descendants. Add the same
Generations controls the member view has (slider + number stepper + "All" per
direction), applied live around the focused person.
Extracts the member page's inline DepthControl into a shared
components/depth-control.tsx and uses it in both, so they stay in sync. The
public chart gains anc/prog depth state + an apply effect (setAncestryDepth/
setProgenyDepth + updateTree) mirroring the member behavior.
tsc clean; next build passes.
