Coaching Radar: live downline triage in admin + member dashboards

- chain.js getCoachingScan(rootId): classifies everyone below a root into
  atRisk (POL forming they can't catch - corrected bought-level rule),
  rollForward (qualified-at-Scintilla with entry rewards covering Ascensus),
  and oneAway (1/2 directs)
- Admin: GET /api/admin/coaching?root= (name-decorated) + "Coaching Radar"
  panel with tiered who/what-to-say/POL-at-stake rows, auto-loaded
- Member dashboards: memberPublic now returns .coach scoped to the member's
  own leg; new "Coach your team" card shows the same triage so every member
  coaches their own team - computed live, no snapshots or cron needed
- Chatbot canned answer + AI system prompt updated to describe the panel
