feat: add TF reference refresh button to Terraform Agent menu

- Add dropdown menu (⋮) in Terraform toolbar with "Atualizar Referência TF" button
- Remove standalone reference-status API endpoint, keep only refresh-reference
- Button triggers `terraform providers schema -json` regeneration with progress feedback
- Shows line count and update timestamp after successful refresh
- Update README with new line counts
