Minor enhancement to OperationStack for readability

[MikeTschudi]

The start function in OperationStack is coded as

  start(type: string, params?: Record<string, unknown>): string {
    const op = {
      type,
      id: getWithDefault(params, "id", createId(`${type}_`)),
      inputs: getWithDefault(params, "inputs", {}),
      cleanup: getWithDefault(params, "cleanup", "n/a"),
      startedAt: new Date().getTime(),
      state: "working"
    } as IOperation;

    this.operations.push(op);
    return op.id;
  }

If it were to be reordered as

  start(type: string, params?: Record<string, unknown>): string {
    const op = {
      id: getWithDefault(params, "id", createId(`${type}_`)),
      type,
      inputs: getWithDefault(params, "inputs", {}),
      startedAt: new Date().getTime(),
      state: "working",
      cleanup: getWithDefault(params, "cleanup", "n/a")
    } as IOperation;

    this.operations.push(op);
    return op.id;
  }

then the structure would align with the structure produced by the startOperation function and make the results easier to read and process automatically.

Currently, the stack appears as
