atlas 52c931c3a7 swarm-nats: require the responder's store identity, and drop its no-store mode
The responder reads the callout xkey before it connects, so a responder
with no secret store no longer starts, and its "deny every agent token,
serve OIDC" mode could not run. That mode is gone: `agent_token::Store`
is built from the settings the xkey load already read, and `authorize`
takes a source rather than an `Option` of one.

On the nix side, `deploy.nats.authBaoClientCertFile` and
`authBaoClientKeyFile` are now asserted at eval when the queue is
enabled. The units' no-identity branches, the copy unit's empty-file
fallback and its "denies agent tokens" message are removed; an absent
leaf file fails `swarm-nats-auth-secrets` like an absent seed does.

# Glue: point the queue's auth-callout responder at the bao leaf minted for it.
#
# ONE PAIRING PER FILE — the swarm-nats-auth principal ← bao, and nothing else.
# Deleting this leaves a queue with no responder identity unless the operator
# names one, which ./swarm-nats.nix refuses at eval.
#
# ⚠️ The minting is NOT here. ./glue-bao-tls.nix holds the CA and signs the
# leaf. What belongs here is the pairing: which paths the responder presents.
#
# ⚠️ Gated on the leaf existing, not on the store being enabled, for the reason
# ./glue-nats-bao-identity.nix states: the hive hosting the queue need not be
# the hive hosting the store.
#
# Everything is `mkDefault`. An operator naming their own paths wins.
