Joe Li b4ce1ff65e test(reports): cover SlackResponse.data scope path and backoff recovery
Close two gaps in the Slack v1-deprecation tests surfaced in review:

- should_use_v2_api scope detection was only exercised with a plain-dict
  response; the production-default path reads the error code via
  getattr(response, "data") on a real SlackResponse. Add a case using the
  existing MockResponse helper so that branch is covered.
- The backoff switch to NotificationUnprocessableException is meant to let a
  transient failure retry and ultimately succeed; only persistent-fail (5x)
  and never-retry were tested. Add a fail-twice-then-succeed case asserting
  3 attempts and the success gauge.
