feat: 유량제어 그룹 버킷 분리 및 현황 화면 개선

- CustomGroupBucket 클래스 신규 생성: 초당/추가 임계치를 별도 LocalBucket으로 분리하여 개별 토큰 조회 가능
  - InflowControlManager 수정: groupBucketList 타입을 CustomGroupBucket으로 변경, makeGroupBucket() 메서드 추가
  - InflowGroupBucketService 단순화: 복잡한 리플렉션 로직 제거, CustomGroupBucket 직접 메서드 사용
  - 현황 탭에 전체 인스턴스 합산 요약 추가 (활성 인스턴스 수, 초당/추가 임계치 합산)
  - 추가 임계치 시간단위에서 '초(SEC)' 옵션 제거
  - 저장 완료 후 리스트 화면 이동 제거
