[Feature Request] Allow copy-pasting of images/other media in Desktop version of app

[strk]

Feature Description

I could not re-open #25 but pasting to FluffyChat/web from Firefox on Ubuntu-22.04 is exactly what I would have loved to be able to do, and failed.

Rationale

Today free desktops often come with a feature that allow you to press the "Print Screen" key on the keyboard to get a screenshot, and then you can copy that screenshot to the clipboard and paste it to various places. FluffyChat/web is NOT a place in which you can paste it, which is frustrating.

Mockup

I don't think a visual mock-up is needed, just see how github itself does it.. paste in a comment and see what happens (same is supporte by opensource git hosters, for example, and I'm told Element/Web also supports this)
