[DT-3774] Fix missing dac_approval column in DacDAO.findAll()

Summary

GET /api/dac never selected dac_approval for the datasets embedded in each DAC, so dacApproval was always null on that response — causing the Manage DAC table's dataset counts to disagree with the DAC profile page (which uses a different endpoint that does select this column). Added the column to the query and mapped it in DacReducer, added a Dac.getDatasets() accessor, and added a DAO test covering approved vs. pending datasets.
