Adds a production-grade in-app version check that prompts users to update when a new build is available. Soft updates are dismissable. Force updates block the app entirely. Configured via FirebaseRemote Config so rollouts can be triggered without redeploying. - Sealed result types (NoUpdate / SoftUpdate / ForceUpdate) for type-safe pattern matching - AppVersionCheckService - AppUpdateGate widget encapsulates listener, route guard and dialog wireup, isolated from save_family_app - Serialized notifier operations prevent race between dismiss and refresh, mounted checks blindar disposal edge cases - Build-aware dismiss persistence via SharedPreferences
