The topbar online count + server-switcher poll, but the sidebar nav
badges (firing-alert "1", update chip) were static Blade — they only
updated on a page navigate/refresh, out of step with the live shell.
The sidebar can't itself be a Livewire poll (that would break its
request()->is() active-nav states). Instead: a tiny `navBadges` Alpine
island on the <nav> polls GET /shell/badges.json every 15s and updates
the [data-nav-badge] chips in place. The badge chips are now always in
the DOM (hidden at zero) so the poller can reveal/hide them without a
re-render. Counts come from the same cached+busted model helpers the
render uses (AlertIncident::firingCount / AuditEvent::threatLoginCount24h
/ ReleaseChecker::updateAvailable — all cache-only, no per-poll query
storm); the endpoint zeroes alerts/threats for non-manage-panel roles.
Verified live in a browser: with an incident fired mid-session, the alert
chip flips to "1" within one poll cycle with NO page refresh, zero
console errors. New ShellBadgesTest (auth + gating + count); the release
badge test updated for the always-present-hidden chip. 753 tests.
