feat: Spring Security 설정 및 JWT, OAuth2 로그인 통합
- CORS 설정: 로컬 개발 환경에서의 접근 허용 (http://localhost:8080, http://localhost:3000) - OAuth2 로그인: 구글 로그인 후 성공 시 CustomOAuth2SuccessHandler 호출 - JWT 인증: JWT 토큰을 처리하는 TokenAuthenticationFilter와 예외 처리 필터 추가 - 세션 관리: 항상 세션 생성하도록 설정 (SessionCreationPolicy.ALWAYS) - 인증 및 권한 설정: API 문서 및 구글 로그인 페이지를 제외한 모든 요청에 대해 인증 필요 - 예외 처리: JwtAuthenticationEntryPoint와 CustomAccessDeniedHandler를 통한 예외 처리
