Fix datetime object handling in OpenAPI schema generation

[Soroushsrd]

Description

This PR fixes #1124

Summary

This PR fixes the OpenAPI schema generation for endpoints that return datetime objects. Previously, the application would fail to start with an AttributeError when attempting to generate OpenAPI documentation for endpoints returning datetime.datetime or datetime.date objects.

Changes made:

• Added special handling for datetime.datetime and datetime.date types in schema generation
• Added proper OpenAPI schema type ("string") and format ("date-time"/"date") for datetime objects
• Added unit tests for datetime schema generation
