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.

+ *
+ * Why this exists: run-android opens Metro by running `cmd.exe /C
+ * launchPackager.bat` in a new window, and the first thing that script does is
+ * `call .packager.bat` — a bare name, resolved from the current directory.
+ * Tools started from inside VS Code (Claude Code among them) carry
+ * `NoDefaultCurrentDirectoryInExePath=1`, which tells cmd not to look in the
+ * current directory. The call then fails, the project paths it would have set
+ * stay empty, Metro dies with `Cannot find module 'D:\cli.js'`, and because the
+ * window gets no stdin its closing `pause` returns at once. The Metro window
+ * flashes and is gone, and the app has no bundle to load.
+ *
+ * The setting is dropped for this command only. Everything else passes
+ * through, so this takes the same flags as the CLI:
+ *
+ *   npm run android
+ *   npm run android -- --mode release
