🎉 feat(ci): aggiungi pipeline Capacitor Android riutilizzabile

- Nuovo workflow capacitor-android.yml con build debug e release
- Input configurabili: runner, node-version, java-version, build-type, output-format
- Supporto APK (sideload/test) e AAB (Play Store) via output-format
- Firma release tramite keystore in base64 (secret)
- Setup google-services.json opzionale per Firebase
- Cache npm + Gradle per performance
- Upload artifact automatico (retention 14 giorni)
- Esempi consumer: ci.yml, release.yml, maintenance.yml
