MichaelandClaude Fable 5 c096532fec fix(android): sign release APK with a stable keystore in CI
Release builds were signed with the debug keystore. On the GitHub runner
that keystore is generated fresh on every build, so each CI APK carried a
different signature and Android refused to install it over an existing
version ("App not installed").

- build.gradle.kts: read android/key.properties when present and use it
  as the release signing config; fall back to debug otherwise so local
  `flutter run --release` keeps working.
- build-apk.yml: decode the keystore from ANDROID_KEYSTORE_* secrets into
  android/key.properties before building, and fail early if any secret
  is missing instead of silently signing with a throwaway key.
