access: keep an SSH key's comment

A key's line was stored as the key alone (`ssh-ed25519 <base64>`), whatever comment it
came with, both from `PUT /auth/keys/<name>` and from `--bootstrap-keys`. Now its
comment is kept after it (`PublicKey::kept_line`), the spaces between its words made
one. The comment checks nothing: every use of a key parses the line, and the parse
reads the key alone.
