feat(ui/alerts): CMD-K sources for alerts + alert rules

Extends operationalSearchData with open alerts (FIRING|ACKNOWLEDGED) and
all rules. Badges convey severity + state. Selecting an alert navigates to
/alerts/inbox/{id}; a rule navigates to /alerts/rules/{id}. Uses the
existing CommandPalette extension point — no new registry.
