New chrome-less (portal) route group with /portal/[clinic], a card-style choice
of "Book an appointment" vs "View my results", and step flows wired to a new
public backend router (src/routes/portal.ts):
- GET /api/portal/:clinic -> clinic name
- POST /api/portal/:clinic/appointments (verifies name+file#, books a confirmed
appointment that appears on the doctor's Appointments page)
- GET /api/portal/:clinic/results (minimal, safe status — no clinical values)
Excluded /portal from the auth proxy redirect so the kiosk loads without a
session. PHI exposure is intentionally minimal (see docs).
