chore(release): v0.3.1 + eas-release.sh script

- package.json + app.config.ts (Expo source-of-truth) auf 0.3.1
- versionCode/buildNumber bleibt 10 (native files schon synced)
- eas-release.sh: build+submit für TestFlight/Play-Internal, default
  iOS, --android/--both flags, version-check-prompt vor build

+#   ./eas-release.sh --ios              # iOS only

+# Profile: `production` (live in eas.json — staging-Backend, app-bundle, m-medium)
+#
+# Voraussetzungen:
+#   - `eas login` einmalig durchgeführt
+#   - Android: serviceAccountKeyPath in eas.json gesetzt (Play-Console-Submit)
+#   - iOS: Apple-Connect-Login wird beim ersten Run abgefragt
