Move Validation DAO to Mongoose

[AustinSMueller]

• Migrated "Validation" DAO code from Prisma to Mongoose
• Replaced the "facet" operation in listPrograms and release service queries. This is incompatible with DocumentDB. The replacement splits the results count and paginated results into separate queries then assembles them into a single response

Pull request overview

This PR updates the backend to support ongoing Mongoose migration work (specifically for Validation) and to improve DocumentDB compatibility by removing $facet usage in aggregation-heavy endpoints/DAOs.

Changes:

• Migrate ValidationDAO to a Mongoose-backed DAO and add a corresponding Validation Mongoose model.
• Remove $facet usage in ReleaseService and ProgramDAO by splitting “results” and “count” into separate queries (DocumentDB compatibility).
• Update GraphQL/router wiring and tests to reflect the Submission constructor parameter removal and the $facet removals.
