Add markdown support for script/category names

Add markdown rendering for script and category titles to improve the
presentation of textual content.

- Introduce reusable `MarkdownText` for markdown rendering.
- Incorporate markdown styling into dedicated SCSS file for clarity.
- Define explicit font sizes for consistent visual experience.
- Apply `MarkdownText` usage across UI for unified markdown rendering.
- Streamline related styles and layout for improved maintainability
- Set font sizes explicitly for better consistency and to avoid
  unexpected inheritence.

This enhancement enables richer text formatting and improves the user
interface's flexibility in displaying content.
