Walkthrough태그 삭제 전에 해당 태그를 참조하는 Todo의 태그 값을 비우도록 변경했습니다. TodoService가 현재 시각으로 수정 시각을 갱신하며, TagService가 태그 삭제 전에 이를 호출합니다. Changes태그 삭제 시 Todo 연결 해제

- Line 36: Update the bulk update query used by clearTagByTagId to set updatedAt
along with clearing tagId, since bulk updates bypass the entity auditing
callback.
- Line 36: Update TodoService.createTodo and updateTodo to validate tag
ownership before saving: allow only default tags or tags owned by the requesting
user, while continuing to allow a null tag ID. Replace existence-only validation
with an accessible-by-user check in validateTagAccessible, using TagRepository
and preserving the existing TAG_NOT_FOUND error for inaccessible tags.
