Deriving ca_certificate from an issue response welds CA distribution to
per-node renewal, so a rotation takes ~90 days to reach the estate, and
issuing_ca is the intermediate alone, which strict path builders reject
as a CAfile.
- add a `ca` subcommand printing {mount}/ca_chain as PEM, unauthenticated
- drop ca_certificate from the issue document and its file output
- order full_chain leaf first
- require only vault.addr for the CA path via config.LoadCA
