feat(web): replace remaining "Soon" stubs with real pages

- Live Tracking: Leaflet map (CDN) showing active truck positions,
  auto-refresh every 10s, sidebar list with speed + last update.
- Finance / Payments: filterable list of payments with mark-paid
  action that runs admin fulfillment.
- Settings: notification-preferences form bound to /me/notification-
  preferences.

Backend:
- New admin payments index endpoint
  GET /admin/payments + POST /admin/payments/{uuid}/mark-paid (moved
  out of /admin/live/* for clarity).

Sidebar groups now reflect what's live: Operations (Trips, Live
Tracking), Planning (Routes, Teams, Trucks, DOPs, Dumpsites), People
(Users, Households, Partner Stores), QR, Areas, Finance, Reports,
Settings. Trip Calendar + Incidents remain "Soon" — backends ready,
UI work pending. Dashboard backend-status copy updated to 13/13
modules / 171 tests.
