[#58]Refactor: userCardDimView 커스텀

- TFBaseCollectionViewCell를 상속받은UserCardViewCollectionViewCell 구현
- DimView Manager 클래스를 따로 빼려고 했지만, 셀이 생성됐을 때의 x, y좌표를 알아야 해서 cell을 커스텀하는 방식으로 구현함.
- 또한, 셀 각각의 view model의 output을 구독하다보니 다른 셀에 대한 트리거를 처리하기 애매해서 미리 셀에 dimView를 추가해놓고
- 셀에서 시작 시간을 output으로 구독해서 타이머가 시작됐을 때 dim view를 hidden하는 방식으로 구현.
- 특정 셀이 다른 모든 셀의 트리거를 알게 할 수는 있지만, 사이드 이펙트 및 비효율적이어서 이렇게 하지 않음.
