fix: address PR #264 review feedback

- Fix token cleanup to use bot user's Basic Auth instead of admin token
  (prevents silent failures when admin token auth is rejected)
- Fix error message to reference correct variable (org_name/ops_name)
- Add idempotency test to smoke-init.sh (runs init twice)
