      summary: Apply rules to existing transactions
      description: >-
        Retroactively apply the given rules to existing unlocked transactions in
        this company. Runs as a background job and returns immediately with a
        `taskId`. Poll GET /tasks to monitor progress.


        **Duplicate-run protection:** returns 409 CONFLICT if an `applyRule`
        task is already in `pending` or `progress` status for this company.
        Running two rule applications in parallel can lead to inconsistent
        transaction state. Call GET /tasks first.
