- These changes makes the API incombatible with previous versions - Added new types for error handling, success responses, and health checks. - Updated health check logic to utilize the new types for better clarity and structure. - Refactored existing handlers to improve response consistency and error handling. - Updated Makefile to include a new target for generating API types from Swagger. - Updated "new agent" API to respond an encrypted cert pair
