Upgrade Prisma 6 to 7 with driver adapter pattern

Prisma 7 requires mandatory driver adapters and moves the generated client
to a custom output path. This migrates the entire monorepo:

- prisma + @prisma/client ^6.16.1 → ^7.0.0 (resolved 7.4.1)
- Generator: prisma-client-js → prisma-client with output to src/generated/prisma
- Datasource URL moved from schema.prisma to prisma.config.ts (Prisma 7 requirement)
- All ~100 files: from '@prisma/client' → from '@muditor/db'
- Every new PrismaClient() now uses PrismaPg adapter
- Added @prisma/adapter-pg + pg driver to packages/db
