선생님/마스터 계정의 학생 계정 관리 화면을 하나로 통합

Browse Source 
- 두 화면이 서로 다른 기능만 갖고 있던 문제 해결: 선생님 화면(엑셀 일괄등록,
  학년 지정, 커스텀 초기비번)에 마스터 화면에만 있던 실시간 학생 목록 조회 +
  기기 리셋(학생이 폰 바꿨을 때 재등록용) 기능을 합침
- 학번을 직접 타이핑하던 블라인드 학년변경/삭제 다이얼로그를 목록의
  행별 액션(학년 칩, 기기 리셋 버튼, 삭제 버튼)으로 교체
- 계정 생성/삭제/학년변경 성공 시 목록 자동 새로고침
- 마스터(2061) 계정의 "학생 계정 관리" 카드도 이 통합 화면으로 연결하고,
  중복되던 student_management_screen.dart / student_management_controller.dart 삭제
