선생님 호출 시스템 추가 (Firebase 버전을 앱 계정 체계로 이전)

별도로 돌아가던 Firebase RTDB 기반 호출 페이지(index.html/teacher.html)에서
발견한 XSS, 익명 접근(아무나 아무 선생님 위치 변경 가능), 이름 위조 문제를
우리 앱 로그인 체계로 재구현하면서 구조적으로 없앴다. 학생은 본인 계정으로만
호출하고 본인 호출 기록만 보이며, 교사는 본인 위치만 수정하고 본인이 받은
호출만 본다. TTS 대신 FCM 푸시로 대체. 시간표 데이터의 "김지"→"조신현" 오타도
"조신"으로 수정해서 옮겼다.

// 📍 선생님 위치 등록 화면(교사용) (UI 전용). 본인 위치를 바꾸고, 받은 호출을 확인한다.
// 서버 통신/상태는 lib/function/teacher_location_controller.dart가 담당한다.
