Feat: 모듈 구조 변경 및 토큰 로직

* Refactor: NetworkService, Persistence 모듈 DataSource 모듈 합치기

* Refactor: Then 외부 라이브러리 제거 및 사용 코드 제거

* Feat: TokenManager 구현

* Refactor: Endpoint에 isAuthorized 값 추가

- Endpoint에 isAuthorized 값 추가 (인증이 필요한지 여부)
- 그렇다면 Endpoint 만들 때 header에 TokenManager에서 accessToken 빼와서 저장

* Refactor: UserDataRepository에 token 재발급 로직 추가

* Feat: 로그인 시 소셜 로그인 타입, 프로필 이미지 저장

- 카카오 로그인 시 nickname, profileImageUrl을 KakaoSDK에서 받아와 저장하도록 로직 추가
- 카카오, 애플 로그인 시 소셜 로그인 타입 저장하도록 로직 추가

* Fix: 온보딩 서버 Request Enum 값 변경

- 온보딩 서버 Request Enum 값 변경
- 온보딩 UI 수정 (SubTitle 여부)

* Feat: UserDataRepository에서 토큰 재발급 가능 여부에 따라 앱 진입점 분기처리

* Fix: 토큰 재발급 로직 Response 타입 변경

- TokenResponseDTO 구현
- reissue response 타입 교체

* Style: 불필요한 주석 제거

* Style: UserDataRepository 오타 수정

* Refactor: 코드 리뷰 반영

- NetworkService에서 endpoint.isAuthorized 값 확인하여 헤더에 토큰 값 세팅해주는 로직으로 수정
- 카카오 유저 정보 (닉네임, 프로필 이미지 URL) 메인스레드에서 동작하는 것 제거
- SceneDelegate에서 SplashView를 먼저 표시하고, reissueToken 결과에 따라 rootViewController 교체하도록 구조 개선

* Refactor: import SnapKit 추가
