feat(dashboard): doctor dashboard with red zones, patient card, live alerts and patient connect

- Patient list sorted red -> yellow -> grey -> green with KPI row, trend arrows,
  7-day adherence bars, discontinuation-risk badge with factor tooltip.
- Patient card: scales with severity bands from config/scales (unscheduled marked),
  mood/sleep/alcohol small multiples, dose heat-strip, alerts feed with ack,
  safety plan, AI summary with disclaimer.
- Live alerts: st.fragment(run_every=2.5s) polling, toast + pinned acute banner on
  every page; full rerun on new alert only on doctor pages.
- Connect form -> POST /patients/connect -> code, QR, deep link.
- Thin httpx ApiClient over the frozen schemas with graceful "API недоступен".
- app.py discovers dashboard/pages/*.py automatically (st.navigation); demo pages
  of #17 plug in by adding a file.
