Add all native dependencies for remaining phases

Batch-install native modules to minimize EAS build credits:
- @maplibre/maplibre-react-native — map view for routes (Phase 3)
- @sentry/react-native — crash reporting and error tracking
- expo-sqlite — offline route storage (Phase 5)
- expo-notifications — push notifications (Phase 7)
- expo-location — GPS for activity recording (future)

All registered as Expo config plugins. Requires one new EAS build
to include the native modules.

Also:
- Use npx eas-cli in build scripts (not global eas)
- Add pnpm dev:ios / dev:android root scripts using eas build:dev
- Fix expo-doctor: add expo-constants, expo-linking, dedupe react
