feat(app): More info for studysets, paths, notes and PDFs

Wherever the old menus offered it: the studyset's options, a path's
(in the list and in the runner), a note's, and a PDF's, all on the
shared sheet the cards use: when it was made (from its UUID v7 id) and
last changed where that is kept, its ids to copy (parent, studyset,
PDF), and for a PDF its file.
