across Bills, Classes, ClassroomRentals, ClassroomSchedule, Classrooms, Deposits,
Expenses, OperationLogs, Permissions, Roles, RoomVisual, Rooms, Students,
Tenants, Users
- Add Empty component via Table locale prop on list pages: Bills, Classes,
ClassroomRentals, Classrooms, Deposits, Expenses (room+personal), Occupancies,
Rooms, Students, Tenants, Roles
- Add batchLoading state to batch delete/update operations: Bills (batchDelete,
batchUpdateStatus), Expenses (batchDeleteRoom, batchDeletePersonal),
Occupancies (batchCheckOut, batchDelete), Rooms (batchDelete),
Students (batchDelete)
- Add refreshLoading indicator to Dashboard header when re-fetching data
