[#454] Infra 레이어에서 Domain 레이어 의존성을 제거한다 (#469)

* chore: TodoService의 Domain 의존성 제거

* chore: WebPage 데이터 흐름에서 Domain 에러 의존성 제거

* refactor: 도메인쪽 에러로 매핑하는 메서드이므로 toDomain()으로 수정

* refactor: 불필요 import문 제거

* refactor: 공통 설정 모델을 Core로 이동

* refactor: 인증 에러를 Data와 Domain 경계에서 매핑하도록 정리

* refactor: PushNotificationService의 Domain 의존성 제거

* refactor: TodoCategoryService 응답을 Data 모델로 분리하여 Domain 의존성 제거

* chore: Infra 레이어에서 Domain 레이어 의존성 완전 제거

* refactor: TodoCategory 선호도 중복 확인 로직 개선
