Fix Robocopy deployment and Laravel pipeline (#279)

## Fix Robocopy deployment step

# Deployment workflow: handle Robocopy exit codes (0, 1, 2 = success)
# Laravel pipeline: use .env.local.example for validation

- Updated `.github/workflows/deploy-mwnf-svr.yml` to treat Robocopy exit codes 0, 1, and 2 as success, preventing false errors in CI/CD.
- Updated `.github/workflows/laravel.yml` to use `.env.local.example` for environment setup and validation, improving pipeline reliability.

These changes ensure robust deployment and validation for Windows-based Laravel environments.

Admin will merge this PR directly for this deployment.
