fix(test-app): auto-detect Android SDK and allow build without adb

Previously, the build script would skip Android builds entirely if
adb was not in PATH, even though adb is only needed for installing/
launching apps, not for building APKs.

Changes:
- Added find_android_sdk() function that automatically detects SDK
  location via ANDROID_HOME, ANDROID_SDK_ROOT, existing local.properties,
  or common default locations (macOS/Linux)
- Automatically creates/updates android/local.properties with detected
  SDK location
- Removed early exit when adb not found - build now proceeds without adb
- Moved adb check to only when installing/launching apps (--run flags)
- Updated warning messages to clarify adb is only needed for install/launch

This allows developers to build APKs even when Android SDK platform-tools
are not in PATH, improving build script usability.
