Keep recovered steering from releasing a stopped queue.

Recovery preserves the original user/web or user/mobile origin. sentByUserFromClient excludes steerFollowUpOfRunId, but not restartContinuationOfRunId.

If Stop interrupts recovered S1 between the S1 and S2 dispatches, S2 can pass the new sibling exception while S1 is still running. S2 then clears existing queue holds as a client send. Queued work can resume after Stop.

Exclude restart continuations from the client-send classification. Add a focused case that orders Stop between the recovered dispatches.

Review comment at @apps/server/src/orchestration-v2/EffectWorker.ts at line 140:
Update the sentByUserFromClient classification in EffectWorker so restart continuations identified by restartContinuationOfRunId are not treated as client sends, preserving queue holds after Stop. Add a focused test that stops between the recovered S1 and S2 dispatches and verifies queued work remains held.

Propagate settings-read failures so steering recovery can retry.

If settings.getSettings fails, this code returns successfully without dispatching any steering. The worker then marks the follow-up effect succeeded, even when retry attempts remain. Accepted steering receives no delivery attempt.

Keep settings-read failures in the error channel. Reserve successful early returns for settings that explicitly disable continuation.

Review comment at @apps/server/src/orchestration-v2/EffectWorker.ts around lines 185 - 186:
Remove the success fallback around settings.getSettings in the EffectWorker flow so settings-read failures remain in the error channel and can be retried. Keep the early return only for settings that explicitly disable continuation.
