Replace WYSIWYG editor with Markdown editor across all relevant models and admin fields. Add utilities for rendering and stripping markdown. Adjust serializers, views, and templates to support markdown content. Introduce `PastedImage` model and upload endpoint for handling inline image uploads in markdown.
