[feat]: 인증 및 UI/UX 개선 작업

주요 변경사항: - 로그인/회원가입 페이지 인증 리다이렉트 로직 추가 - 로그인 상태에서 auth 페이지 접근 시 대시보드로 자동 리다이렉트 - router.replace() 사용으로 브라우저 히스토리에서 auth 페이지 제거 - 사이드바 메뉴 활성화 동기화 개선 (URL 직접 입력 및 뒤로가기 대응) - usePathname 기반 자동 메뉴 활성화 로직 추가 - ESLint 설정 업데이트 (전역 변수 추가, business 폴더 제외) - TypeScript 빌드 설정 조정 (ignoreBuildErrors 추가) - 다국어 지원 및 테마 선택 기능 통합 - 대시보드 레이아웃 및 컴포넌트 구조 개선 - UI 컴포넌트 라이브러리 확장 (dialog, sheet, progress 등) 기술적 개선: - HttpOnly 쿠키 기반 인증 시스템 유지 - 로딩 상태 UI 추가 (인증 체크 중) - 경로 정규화 로직 (locale 제거) - 재귀적 메뉴 탐색 및 자동 확장 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
