Replace the customer app with Doormile CX

Book a pickup, track it to delivery — the rebuilt customer app.

- Design language from doormile-screens.html: brand #8F0F06, Manrope +
  Geist Mono (variable fonts), bordered cards instead of shadows, crimson
  brand headers, sliding tab indicator, mono for anything read digit by digit.
- lib/data (one live API implementation, plus a debug-only offline fake),
  lib/state, lib/ui (tokens, widgets, screens).
- 84 tests, plus a design snapshot harness that renders every screen with the
  real fonts: flutter test test/design_snapshot_test.dart --run-skipped
  --update-goldens

This replaces the previous app (pubspec 'doormile', app id
com.doormile.customer). That tree remains in history at 6c7d656; note its
android/app/google-services.json is not carried over, and the application id
here is in.doormile.customer.
