feat: add venv support and restructure Pulumi config for non-interactive IaC workflow

- Use PROJECT_ROOT for all module paths (Pulumi, Terraform, Ansible)
- Move requirements.txt to project root and auto-create .venv if missing
- Setup pip dependencies before pulumi up
- Add non-interactive pulumi stack select/init
- Clean up old pulumi/requirements.txt
- Update .gitignore to exclude .venv, Pulumi and Terraform state files
