Pull request overview

Migrates the backend Batch data access layer from the Prisma-based DAO to a Mongoose-backed DAO/model, aligning Batch persistence with the project’s existing Mongoose infrastructure while keeping service-level behavior consistent.

Changes:

• Added a Mongoose Batch model/schema and switched BatchDAO to extend MongooseGenericDAO.
• Updated BatchService.listBatches to pass Mongoose-style pagination/sort options to the DAO and tightened the corresponding unit test expectations.
• Expanded DAO error-handling tests to mock Mongoose query behavior (lean/select/sort/limit chains) and added coverage for success-path mapping.
