fix(mobile): narrow closed-train states and degrade gracefully on API error

Review follow-ups:
- Drop IN_REVIEW / WAITING_FOR_REVIEW / PROCESSING_FOR_APP_STORE from the
  closed set. Those versions still accept TestFlight builds, so treating them
  as closed would auto-bump the marketing version mid-beta-iteration — the
  exact workflow this change is meant to preserve. Only approved/released/
  removed states terminally close the train (the 90186 case).
- Rescue API errors in version_train_closed? and assume open, so a transient
  ASC blip degrades to today's behavior instead of failing the release.
