feat(stand): add FullPipe DEV stand for vc_vdc and document 500 error fallback plan

- Added DEV_STAND/FullPipe with modular configuration for vc_vdc resource creation:
  - versions.tf: Terraform >= 1.5.0, provider nubes 2.0.1
  - provider.tf: nubes provider config with DEV gateway endpoint
  - variables.tf: variables for vdc (cpu=8, mem=32, guaranteed=0, fast storage=200GB)
  - vdc.tf: nubes_vc_vdc resource definition supporting org name or UUID
  - outputs.tf: vdc_id, vdc_name, vdc_state_params
  - terraform.tfvars.example: example values without secrets
- Added docs/DEBUG_REPORT_VC_VDC_500.md documenting API 500 issue in Lucee backend:
  - Error: getResourceRealmConfig fails casting Struct to string on GET /instanceOperations/{opUid}?fields=cfsParams
  - Planned changes in provider/internal/core/client.go:
    Implement graceful fallback in createInstanceWithContext to skip hard-failing
    when GET ?fields=cfsParams returns 500, since vc_vdc ref parameters (organization_uid)
    are already resolved to UUID and remaining parameters are literals/numbers.
