style: tofu fmt the two files my multi-env change reformatted

Whitespace-only. `tofu fmt` realigned two spots that my Phase A edits
shifted:
- app_roles/main.tf: the REASSIGN revocation-statement trailing comment
  re-aligned after the GRANT line gained ${local.owner_role}
- variables.tf: the applications object keys re-aligned after adding the
  longer `envs` key

The two pre-existing unformatted files (factory_auth.tf, terraform.tfvars)
are left as-is — they were already unformatted on origin/main and are
outside this PR's scope.
