- Introduced rate-limiting to `/auth/*` routes with configurable limits using `SlowAPI`. - Added `/health` endpoint for service monitoring and load balancer health checks. - Updated `requirements.txt` to include `SlowAPI` for rate limiting. - Implemented tests for rate-limiting and health check functionality. - Enhanced configuration and security with updated environment variables, pinned dependencies, and validation adjustments. - Provided example usage and extended coverage in testing.
