feat(events): shadcn Alert replaces hand-rolled callout aside

Install the shadcn-vue Alert primitives (Alert / AlertTitle /
AlertDescription + the alertVariants cva) at
src/components/ui/alert. Files mirrored from the registry JSON.

EventsView: the bouge.ariege.io heads-up at the top of the listing
was a hand-styled <aside> with a <p> kicker and a body paragraph;
swap to <Alert><AlertTitle>…</AlertTitle><AlertDescription>…
</AlertDescription></Alert>. Keep bg-card + text-foreground/85
overrides so it still reads as a quiet card on the green hero band
rather than the variant default.
