## Summary by cubic
Switch @calcom/prisma to use relative imports for client and enums. This removes self-references, stabilizes builds, and improves type resolution.
- **Refactors**
- Replaced imports from "@calcom/prisma/*" with local "./client" and "./enums" across extensions, selects, mocks, and availability check.
- Updated safeJSONStringify parameter type from any to unknown.
- Minor formatting cleanup in zod-utils.
