refactor: rename site bcn01 to BCN01-LAB

- Rename sites/bcn01/ -> sites/BCN01-LAB/
- Update S3 backend key: bcn01/terraform.tfstate -> BCN01-LAB/terraform.tfstate
- Rename Terraform module: bcn01 -> bcn01_lab
- Update working-directory in apply.yml and plan.yml
- Update job/step names to BCN01-LAB

NOTA: mover manualmente en S3 el objeto
  bcn01/terraform.tfstate  ->  BCN01-LAB/terraform.tfstate
antes de hacer terraform init en el nuevo directorio.
