The parent query for agent detail uses routeAgentRef (URL key like
"claudecoder") in its cache key, but ConfigurationTab and rollbackConfig
only invalidated by agent.id (UUID). This meant the refetch never fired
when navigating by URL key, so the dirty overlay was never cleared and the
save button stayed visible indefinitely.
Add urlKey-based invalidation to match the pattern already used by other
mutations in the parent component.
