remove Expo project and all related files

Remove the entire Expo/React Native application: routes (app/), source
code (src/), assets, iOS native build, config plugins, StoreKit config,
npm dependencies, TypeScript/ESLint/Vitest configs, and Expo-specific
documentation. The repository now contains only: admin-web, supabase,
youtube-worker, tabatago-swift, docs, scripts, and CI/tooling configs.
