Subject: [PATCH] Add anonymous sign-in provider support to user service and
 types.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- `Provider` 타입에 `anonymous`를 추가하여 비회원 인증 상태를 명시적으로 처리합니다.
- `userService`의 인증 제공자 식별 로직에 `anonymous` 타입을 포함하여 예외 발생을 방지하고 유연한 사용자 관리를 지원합니다.
