Implement liquidation for a specific period

resolve #19

Changes

sequence

AS-IS

既存の清算シナリオは「清算→清算額計算→清算完了」で、全期間での清算、すなわち合計支払額の不均衡を解消することしかできない。
この清算では、各ユーザーの支払い合計額を payAmount で保持しているのでそれを使っている。

CHANGE-TO

AS-ISの清算シナリオに1ステップ追加し、期間を指定できるようにする。「清算→期間選択→清算額計算→清算完了」。
この場合、指定された期間内に起こった支払いのみを清算する。

個々の支払いの履歴が必要となるため、payments collectionを今回追加する。

期間の入力にはわかりやすさのため 日時選択アクション を使用する。postback dataの保存が必要のため新たにstoreにliquidations collectionを用意する。

Limitation

• payments collectionを使り始めたのが 2023/06/23 〜なので、ユーザーが選択できる期間はそれ以降

Refactoring

• flex message packageの作成
  • 標準のテンプレートであっても flex message で自作する方がデザイン性が良く、数が増えたため
• 清算を evenUp から liquidation に変更（が、めっちゃタイポする）
• storeのコードのファイル分割

Future Works

• 選択された期間にあるpayment documentの数がそのままread回数となるため、abusingされると死ぬ。documentの最大数を制限したり、事前に1日/1週間等で合算しておくなどの工夫が必要。これはダッシュボードを作るときにも同様に問題になる...。

Note: You didn't use the -out option to save this plan, so Terraform can't
guarantee to take exactly these actions if you run "terraform apply" now.
