Document every repo in Sphinx, catalog PDFs, and verae-ops

Add missing package READMEs, expand Sphinx to all runtime modules,
publish a LaTeX/PDF README book, and add verae-ops for Docker,
Proxmox, VMs, dedicated hardware, and service linking. Catalog
defaults to public PDF links for each module README and samples.
