fix(tksafety): DB 스키마 불일치로 인한 API 500 에러 수정

- departments.name → department_name (3곳)
- users → sso_users 테이블 참조 수정 (7곳)
- tbm_sessions.start_time → created_at (존재하지 않는 컬럼)
- tbm_team_assignments JOIN: ta.user_id → ta.worker_id
- workers leader JOIN: leader.worker_id → leader.user_id
- tbm_weather_conditions → weather_conditions 테이블명 수정
