Pull request overview

This PR migrates the PendingPVs data-access layer from Prisma to the existing Mongoose-based DAO infrastructure, aligning pending PV operations with the ongoing Prisma→DocumentDB/Mongoose transition in the backend.

Changes:

• Added a new Mongoose model for the pendingPvs collection.
• Refactored PendingPVDAO to extend MongooseGenericDAO and use the new Mongoose model for findBySubmissionID and insertOne.
• Added Jest unit tests covering DAO behavior and ID mapping, and removed an unused DB constant import from the GraphQL router.
