test: address review comments on waitForJob and waitForCondition usage

- waitForJob: fix falsy-status early-exit — `status !== 'IN_PROGRESS'`
  exits immediately when job is not found / response is malformed,
  rather than polling until timeout
- northwind: replace redundant post-waitForCondition assertions with a
  .catch() re-throw that appends lastResponse.text to the timeout error,
  making failure messages reachable and useful (#2 and #3)
