The Software Updates section showed a red "version mismatch" warning next
to "Check for Updates", but that button only queries for a newer release and
can never reconcile a frontend/backend mismatch — so users clicked it, saw a
spinner, and the warning stayed put.
Reframe the warning as an informational Alert placed at the bottom of the card,
decoupled from the update button, and give it a concrete resolution path
(restart to finish applying the update; reinstall the latest version if it
persists). It now names the two versions in play instead of the opaque
"client / AppConfig" wording.
