feat(tkfb): 연차 데이터 정본 전환 — vacation_balance_details → sp_vacation_balances

대시보드 + 연간 연차 현황 페이지의 읽기를 tksupport 정본 테이블로 전환.
- dashboardModel: getVacationBalance worker_id → user_id, sp_vacation_balances
- dashboardController: worker_id 전달 제거, user_id 직접 사용
- vacationBalanceModel: 읽기 함수 3개 sp_vacation_balances로 전환
  (쓰기 함수 deductByPriority 등은 vacation_balance_details 유지)
- remaining_days: STORED GENERATED 대신 (total_days - used_days) AS 계산
