Next.js's production build type-checks the whole repo by tsconfig.json's
default include glob, which picked up mobile/'s .tsx files once the
Docker image's git checkout finally included mobile/ (first pull to
include it) — none of mobile's own dependencies (react-native, expo-router,
...) are installed in that container, so the build failed outright.
mobile/ is now excluded from tsconfig.json and .dockerignore; it's a
separate app with its own tsconfig/package.json and was never meant to be
type-checked or shipped as part of the web image.
Also completes the mobile EAS/FCM push setup (app.json's extra.eas.projectId
and googleServicesFile, google-services.json gitignored) and adds a 15s
timeout around getExpoPushTokenAsync so a device that can't reach FCM fails
visibly instead of hanging silently forever.
