refactor(frontend): 공통 모듈 common/ 분리 + OpenLayers 제거 + path alias 설정

- OpenLayers(ol) 패키지 제거 (미사용, import 0건)
- common/ 디렉토리 생성: components, hooks, services, store, types, utils
- 17개 공통 파일을 common/으로 이동 (git mv, blame 이력 보존)
- MainTab 타입을 App.tsx에서 common/types/navigation.ts로 분리
- tsconfig path alias (@common/*, @tabs/*) + vite resolve.alias 설정
- 42개 import 경로를 @common/ alias 또는 상대경로로 수정
