fix: release beds/lockers in batchCheckOut

The batchCheckOut method was not releasing assigned beds and lockers
after checkout, leaving them orphaned as 'occupied'. Added the same
release pattern used in checkOut() — using runner.manager.update()
since batchCheckOut operates inside a QueryRunner transaction.
