hive-tls: fail swarm-services-cert when the store identity is absent

Browse source 
A hive fronting no swarm name fetches the store's pki root presenting its
reader certificate. When deploy.bao.clientCertFile or clientKeyFile is unset,
or either named file is not readable, the unit now exits 1 with a message
naming both options and their paths, instead of exiting 0 with the root
missing from the trust bundle.

The module-eval cases that asserted the quiet skip assert the failure
instead, and a new case covers the named-but-absent files.
