defiQUG e8ae376e90 Enhance API services with validation and error handling improvements
- Integrated Zod validation schemas across various API routes to ensure input integrity and improve error handling.
- Updated `mapping-service`, `orchestrator`, `packet-service`, and `webhook-service` to utilize validation middleware for request parameters and bodies.
- Improved error handling in webhook management, packet generation, and compliance routes to provide clearer feedback on request failures.
- Added new validation schemas for various endpoints, enhancing overall API robustness and maintainability.
- Updated dependencies in `package.json` to include the new validation library.
