fix: resolve turbo build failures blocking Railway deployment

- Add missing logger imports in MessageHandler.ts and pedagogy.ts
- Remove conflicting fastify.d.ts (prisma: PrismaClient vs prisma: any)
- Consolidate all Fastify type augmentations in types/fastify.d.ts
- Import @fastify/multipart types to restore req.file() signature

All 7 packages now pass pnpm turbo run build (matches Dockerfile builder step).
