Set up Sentry crash reporting for mobile app

- Initialize @sentry/react-native with dedicated mobile project DSN
- Wrap root layout with Sentry.wrap() for unhandled error capture
- Configure Sentry plugin with org (trails-qq) and project (mobile)
  for source map uploads during EAS builds
- Disabled in dev, full tracing in production
