fix: Resolve registration API 500 error and proxy configuration

- Fixed undefined variable 'db' in register endpoint (renamed to 'database')
- Updated Vite proxy configuration to use Docker container names
- Fixed proxy target from localhost to backend container
- Added host: true to Vite server config for Docker compatibility
- Registration endpoint now works correctly through frontend proxy

All registration functionality is now fully operational:
- Frontend form validation
- API proxy routing
- Backend user creation
- JWT token generation
- MongoDB data persistence

+- JWT 토큰 발급 및 검증
+- 사용자 인증 및 권한 관리
+- 애플리케이션 등록 및 관리
+- 인증 히스토리 추적
