fix(e2e): add build-tools 30.0.3 and platform-tools hash override

Fixed two Android SDK issues:

1. **Build-tools version mismatch (Linux CI)**:
   - RN 0.72 (E2E-compat) requires build-tools 30.0.3
   - Plugin default is 35.0.0
   - Gradle fails with "SDK directory is not writable" when trying to auto-download
   - Added ANDROID_BUILD_TOOLS_VERSION="30.0.3" override in E2E-compat
   - Updated GRADLE_OPTS aapt2 path to match

2. **Platform-tools hash mismatch (macOS dev)**:
   - platform-tools_r37.0.0-darwin.zip hash has changed
   - Added hash-overrides.json with correct hash:
     094a1395683c509fd4d48667da0d8b5ef4d42b2abfcd29f2e8149e2f989357c7
   - Note: This only affects local macOS dev, not Linux CI

Changes:
- examples/E2E-compat/devbox.json: Add ANDROID_BUILD_TOOLS_VERSION
- examples/E2E-compat/devbox.d/.../hash-overrides.json: New file with platform-tools hash

Fixes: E2E Android (RN 0.72) timeout due to Gradle build failure
