frontend: Support displaying images/videos/pdfs in the workspace

[xingyaoww]

What problem or use case are you trying to solve?

Images are not properly rendered in the Code Editor (though maybe it is not supposed to do that... -- I'm open to discussion about this).

Describe the UX of the solution you'd like

I kind of expect a VSCode-like experience that it can display some simple media file (jpg, png, or even mp4 and pdf) and show an error message when it encounters a binary file type (e.g., .exe) that it does not support.

Do you have thoughts on the technical implementation?

Describe alternatives you've considered

Additional context

[amanape]

For images and videos it may be as simple as rendering an img or video element given the extension/path.
