vitepress: Fix reloading dev server

Javascript/Nodejs/Vite fun: we use JS dynamic import to load the data files.

When reloading the dev server, these imports aren't executed again, since the
namespace that was imported already exists.

This means that any modification of the data is actually global, since the
object references the original data. The data manpulation code is assuming
that the data is "fresh" from the data files, so this breaks things.

Solution: when loading data, do a deep clone and pass that to our data
manipulation functions.
