fix(build): add Capacitor sync and auto-fix for Android test app builds

Fixed Android test app build failures by ensuring Capacitor is synced
before building and automatically fixing missing file references.

Changes:
- Add Capacitor Android sync step before building test app
  - Runs `npm run cap:sync:android` to create required project structure
  - Ensures `:capacitor-cordova-android-plugins` project exists before Gradle resolves dependencies
- Add automatic fix for missing cordova.variables.gradle reference
  - Detects when capacitor.build.gradle references non-existent file
  - Automatically comments out problematic `apply from` line
  - Uses platform-agnostic sed command (handles macOS and Linux)
  - Provides clear logging about what was fixed
- Reorganize build flow to match iOS pattern
  - Sync Capacitor first, then navigate to platform directory
  - Apply fixes, then build

This fixes the build error:
  "Could not resolve project :capacitor-cordova-android-plugins"
  "No matching variant of project :capacitor-cordova-android-plugins was found"

The build now completes successfully even when:
- Capacitor hasn't been synced yet
- capacitor.build.gradle references missing files
