fix: schedules lookups test mock missing classroomRepo constructor arg

The SchedulesService constructor expects 5 repository arguments.
The test only provided 4, passing {} as never for classroomRepo.
Added classroomRepo mock with find() returning full selected columns.

Fixes: schedules.lookups.spec.ts — 'returns scoped classes and
minimal classrooms for schedule viewers'
