PR Summary

• Enhanced User Object Structure
  The id property was added to the OpenAPI configuration for user objects. This change assists in identifying individual user data records more easily.

• Improved Tag Filtering
  The logic in the filterTags function has been updated to include added flexibility. Now, if the requiredTags list is empty, it still returns true. This allows the function to continue operating even without specified tags.

• Dynamic Approach in Query Parsing
  We have modified the parseQuery to handle requiredTags[] from the request query. This allows the service to filter tags dynamically based on received requests instead of a static set of tag lists.

• Augmented Author Information in Posts
  The id field for authors is now added in the RenderedPost interface, along with the existing author information. This allows inclusion of the author's ID in the displayed post data, assisting in better identifying authors.

• More Comprehensive Post Rendering
  The renderPost function has been revamped to include the author's ID in the post data. This adds another layer of detail to posts, making author identification easier for users.

• Improved Markdown Rendering
  Markdown rendering was updated to enable line breaks. The breaks: true option was added in the marked function, ensuring that texts typed in Markdown respect line breaks, enhancing readability.
