Build Android APK via Myket maven mirror (verified)

- Myket mirror serves maven2 layout at root https://maven.myket.ir (proxies
  Maven Central + Google/AGP); android/build.gradle uses it
- gradle-mirror.init.gradle template injects the mirror into all modules and
  pins build-tools 36 + Java 17 (this env lacks build-tools 35 / JDK 21)
- ANDROID.md updated with the exact working build command
- Produces app-debug.apk (~4.5 MB)
