mints a dav app password, renders a configuration profile carrying both the
caldav and carddav payloads, and parks it behind a single-use five-minute token
that safari can fetch without a session.
one profile with both payloads is not a convenience: ios keys accounts by
server+username, so adding carddav separately gets folded into the existing
caldav account and contacts silently never appear.
the profile holds the password in plaintext, so it is held in memory only —
persisting it would falsify createDavAppPassword's "not stored" guarantee.
signing is opt-in via DAV_PROFILE_SIGN_CERT/_KEY/_CHAIN and off by default;
this box has no tls certificate, tls terminates upstream. signed at mint time
reading the cert from disk, so a renewal needs no restart and no hook.
the download route is registered before the /dav mount because hono matches in
registration order and the sync door's /* would otherwise demand http basic.
