With no live CDN (provider NONE, or every hostname at stage OFF) the
Purge From CDN, Purge Everything and Retry Purge actions said the
requests were "sent within seconds" while the dispatcher skipped them.
Review and Result now carry a warning line ("No CDN provider configured:
purges are recorded only, not sent." or "CDN hostnames are not live"),
from the same status logic CdnPurgeService records (sendingStatus).
The home's Connection, Health and Purges cards say the same, and the
Origin headers card no longer implies a check is scheduled.
