Subject: [PATCH] build: rendi la build Docker riproducibile

- Pinna Flutter a 3.41.9 (ARG FLUTTER_VERSION) in entrambi i Dockerfile
- Aggiunge /opt/android-sdk/build-tools/34.0.0 al PATH (zipalign era missing)
- Sostituisce mount ${HOME}/.gradle con named volume gradle-cache
- Aggiunge --enforce-lockfile a flutter pub get per bloccare le dipendenze
- Aggiunge .flutter-version con la versione Flutter attesa
