Subject: fix(backend): use `prefixItems` in `admin/queue/*-delayed` endpoint
 schema (#14468)

* fix(backend): represent tuples with `prefixItems`

* refactor(frontend): fix type errors

* fix(backend): add `prefixItems` in `SchemaType`

* fix(backend): add `unevaluatedItems: false` to disallow extra items

* refactor(frontend): consolidate `'deliver' | 'queue'` type def into `queue.vue`

* fix(backend): add `unevaluatedItems` in `SchemaType`

 - Fix: 設定変更時のリロード確認ダイアログが複数個表示されることがある問題を修正
 
 ### Server
+- Feat: Misskey® Reactions Buffering Technology™ (RBT)により、リアクションの作成負荷を低減することが可能に
 - Fix: アンテナの書き込み時にキーワードが与えられなかった場合のエラーをApiErrorとして投げるように
   - この変更により、公式フロントエンドでは入力の不備が内部エラーとして報告される代わりに一般的なエラーダイアログで報告されます
 - Fix: ファイルがサイズの制限を超えてアップロードされた際にエラーを返さなかった問題を修正

Subject: fix(backend):
 `Retry-After`ヘッダーが実際には送信されなかった問題を修正 (#14597)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* move rate-limit-exceeded error reporting, earlier

a rate-limit-exceeded error has `kind:'client'`, so the branch that
adds the `Retry-After` would never get taken

(cherry picked from commit 8a982c61c01909e7540ff1be9f019df07c3f0624)

* Update Changelog

* fix

* indent

Subject: Add Sign in with passkey Button (#14577)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Sign in with passkey (PoC)

* 💄 Added "Login with Passkey" Button

* refactor: Improve error response when WebAuthn challenge fails

* signinResponse should be placed under the SigninWithPasskeyResponse object.

* Frontend fix

* Fix: Rate limiting key for passkey signin

Use specific rate limiting key: 'signin-with-passkey'  for passkey sign-in API to avoid collisions with signin rate-limit.

* Refactor: enhance Passkey sign-in flow and error handling

- Increased the rate limit for Passkey sign-in attempts to accommodate the two API calls needed per sign-in.
- Improved error messages and handling in both the `WebAuthnService` and the `SigninWithPasskeyApiService`, providing more context and better usability.
- Updated error messages to provide more specific and helpful details to the user.

These changes aim to enhance the Passkey sign-in experience by providing more robust error handling, improving security by limiting API calls, and delivering a more user-friendly interface.

* Refactor: Streamline 2FA flow and remove redundant Passkey button.

- Separate the flow of 1FA and 2FA.
- Remove duplicate passkey buttons

* Fix: Add error messages to MkSignin

* chore: Hide passkey button if the entered user does not use passkey login

* Update CHANGELOG.md

* Refactor: Rename functions and Add comments

* Update locales/ja-JP.yml

Co-authored-by: syuilo <4439005+syuilo@users.noreply.github.com>

* Fix: Update translation

- update index.d.ts
- update ko-KR.yml, en-US.yml
- Fix: Reflect Changed i18n key on MkSignin
