feat(cover): give books with both media separate ebook and audiobook covers

Keep one cover slot per medium and show the one each surface needs: the
library's shape for the face, square art on audio screens, the ebook slot
for Kobo and OPDS. Legacy covers convert on upgrade or on first read, and a
write that names no slot keeps working for released iOS builds. Also read
the dev client origin from one constant.
