Add Positive Pay, statement guide v1.0, onboarding, and switch every feature on

- Positive Pay on the 12 Oct /pps contract (account number, not account ID):
  OTP enrollment, cheque submit, saved cheques, detail and stop payment.
  Full flow passed on the phone against mobile-banking-backend.lincpay.
- Statement & Mini Statement guide v1.0 (14 Oct): mini statement JSON on
  Home and the Statement screen; dated PDF export with the password rule.
- Onboarding slides and splash screen, Inter font, shared Icon and
  TypewriterText components, nearby branches via OpenStreetMap.
- Every feature switched on; the 14 Oct switch set is kept in
  featureConfig.stage-2026-10-14.ts. Loans run on demo data until the
  backend has /loans routes.
- npm run android wraps run-android for shells spawned from VS Code.
- OpenProject work packages updated to 14-10-2026 status, with screenshots
  of Positive Pay, statement, loans and cards.
