feat(character-gallery): 갤러리 탭 UI/페이징 및 API 연동, DI 적용

- API: CharacterApi에 이미지 리스트 API 추가(characterId, page, size) - VM: 페이징(loadInitial/loadNext), 요청 중복 방지, 마지막 페이지 판단, 누적 리스트 관리 - UI: ProgressBar(배경 #37474F/진행 #3BB9F1, radius 999dp, 비활성) + 좌/우 텍스트 구성 - Grid 3열 + 2dp 간격, item 4:5 비율, 잠금/구매 버튼 UI 적용 - UX: tv_ratio_right에서 ownedCount만 #FDD453로 강조(white 대비)
