Description

Add custom pages for error codes like 403, 404, and 500 for non-development environments.

Background

Currently, error pages (such as 404, 500, 502, etc.) are served with default templates, which may not provide the best user experience. We need to enhance this by adding custom error templates for these specific error codes in the non-development environment.

Feature Details

• Create the custom template for the below error codes
  - 403
  - 404
  - 500
• We can utilize Django handlers, such as https://docs.djangoproject.com/en/4.2/ref/urls/#handler400
• Initially, simple templates can be added for each error code, and the updated templates will be included in this issue.

From a development perspective, the required changes to implement custom templates for error codes can be made initially, and then the final templates will be updated accordingly.
