fix: wait for build workflow to complete before pushing to main

- Modified workflow to wait for 'build-and-deploy.yml' to complete successfully on dev branch
- Prevents 'Required status check build is in progress' error when pushing to main
- Adds 30-minute timeout with 30-second polling interval
- Fails gracefully if build fails, is cancelled, or times out

This fixes the workflow execution failure where pushes to main were blocked because the required 'build' status check was still in progress.
