fix(orchestrator): add prisma generate to Dockerfile and reflect-metadata to vitest setup

Two CI fixes:
1. Orchestrator Dockerfile now copies apps/api/prisma schema and runs
   prisma generate before build. Fixes TS2305/TS2339 errors (PrismaClient
   and model properties not found) in docker-build-orchestrator step.
2. Add reflect-metadata to vitest setupFiles. Fixes class-transformer
   decorator error (Reflect.getMetadata is not a function) in DTO unit tests.
