🐛 Bug Report: `create_row` with `transaction_id` fails — Pydantic Row model requires $createdAt / $updatedAt but transactional responses omit them

### 👟 Reproduction steps

- Create a transaction via `TablesDB.create_transaction()`
- Call `TablesDB.create_row(...)` with a transaction_id
- The SDK's Pydantic Row model fails to deserialize the response

### 👍 Expected behavior

`create_row()` to work inside a transaction?

### 👎 Actual Behavior

Throws this error when calling `create_row()`

```
2 validation errors for Row
$createdAt
Field required [type=missing, input_value={'$id': '69c435146902e250...ns': [], '$sequence': 0}, input_type=dict]

まず Pydantic の Row モデルと TablesDB.create_row() の処理経路を見つけ、次に transaction_id が指定された場合に生成されるレスポンスの形状をモデルの必須フィールドと比較します。transaction create_row() 呼び出しを再現し、そのレスポンスが $createdAt と $updatedAt のバリデーションエラーなしにデシリアライズされることを確認して、修正を検証します。
