Four fixes from the on-host agent bring-up:
1. Bake the real fleet CA into the image. New `fleet_ca` build var (default =
the committed placeholder) file-provisions the trust anchor to
/etc/dot1x/radius-ca.pem — used by wpa_supplicant (RADIUS) AND the fleet-agent
(verify the manager). CI materializes a FLEET_CA secret to a runner-temp file
and passes -var fleet_ca; unset => placeholder (lab). No CA material committed.
2. server-pki.sh installs the agent CLIENT CA as root+intermediate (not root
only). Host TPM certs are leaf-only in NV and signed by the step-ca
intermediate, so a root-only client CA makes the manager advertise only the
root in its CertificateRequest -> Go clients send no cert ("tls: certificate
required") and it couldn't verify a leaf-only cert anyway. bootstrap.sh now
exports intermediate_ca.crt so FLEET_CA_INTERMEDIATE resolves.
3. New `fleet-manager register-host <serial> [-name] [-hostnqn]` subcommand:
seeds/updates an inventory record for a host enrolled out of band (bench
broker, migrated fleet) through the real store, so its agent stream is
accepted. The manual counterpart to the authorise-approve flow.
4. The agent surfaces the authoritative recv-side gRPC status instead of the
bare io.EOF gRPC returns on the send side when the server ends the stream —
so "host is not enrolled" (PermissionDenied) shows up instead of "EOF".
