v0.1.16
Warn when the library directory is empty or archives are missing A common setup mistake: the inpx catalog is imported (metadata only) but the book archives are mounted at a path other than POLKA_LIBRARY_DIR, so every read fails with "not on disk". Surface this explicitly: warn at startup if the library dir is missing/empty, warn after an import if sampled archives are not found, and show the library status + a banner in the admin panel.
