최종 경로 최적화: Program.cs 및 HTTP 클라이언트 경로 수정

## 변경사항
- Program.cs (WASM Client): apiBaseUrl /taxbaik/api/ → /api/
- ClientLogs.razor: HTTP 요청 경로 /taxbaik/api/ → /api/
- Services/TokenRefreshHandler: /taxbaik/api/auth/refresh → /api/auth/refresh
- AdminShell/AdminSidebar: 공개 사이트 링크 /taxbaik → /

## 최종 E2E 테스트 결과
✅ 공개 페이지: 5/5 통과
❌ 관리자 페이지: WASM 부팅 오류 (5/5 실패)

## 경로 최적화 완료 항목
✅ PathBase 제거
✅ Blazor 상대 경로 변경
✅ Razor Pages 상대 경로 변경
✅ API 클라이언트 경로 수정
✅ HTTP 요청 경로 수정
✅ 네비게이션 링크 수정

## 남은 문제
❌ WASM 부팅 단계에서 예외 발생 (원인: 브라우저 콘솔 확인 필요)
