Add MAUI workload installation to GitHub Actions workflows

- Install dotnet workload maui in all workflow jobs
- Add build tasks compilation before main solution build
- Add Android SDK setup for Linux runners
- Ensure proper build order for MAUI projects

This should fix the workload missing errors in GitHub Actions.
