Some unused and some missing Javascript dependencies?

[fabcor-maxiv]

Seems like we might have a bunch of unused Javascript dependencies and some that are missing (!?), see below. Maybe we could investigate further and tidy up.

What do you think @axelboc?

It'd be good to do a bit of a clean-up, you're right.

I'd be very careful about this, though. I'm not sure how depcheck works, but identifying unused dependencies can be tricky. For instance, some of the dependencies reported are peer dependencies, like plotly.js (peer dep of react-plotly.js).

As a safety check, after removing a dependency, one can run pnpm install --resolution-only to make sure there aren't any peer dependency issues.

I'll see if I have time to take a look.

Yes, I picked the depcheck tool at random, and I for sure do not know enough about this topic to judge its output. Definitely needs closer investigation. Not a high priority, obviously. There might be some low-hanging fruit in terms of cleaning. And maybe the "missing dependencies" part is an actual issue (I do not know).
