Same shell pattern as top-buh/top-finance/thbd-portal: desktop top nav
stays >=lg, a fixed bottom tab bar takes over below it. Only 2 nav
links here so both fit directly, no overflow menu needed.
Also adds manifest.webmanifest + 192/512 icons (rendered from the
existing icon.svg) and appleWebApp/viewport metadata so the app can be
installed to a phone's home screen.
Nudged ticket-toasts.tsx's fixed bottom offset so it clears the new
bottom nav bar on mobile instead of overlapping it.

The SSE + in-page toast/sound system only works while the tab's JS is
actually running — Chrome (and other browsers) freeze a backgrounded
tab's JS after a stretch of inactivity to save power, so notifications
silently stop regardless of how correct the SSE/toast code is. A Service
Worker is the only mechanism that keeps receiving events independent of
the tab's own lifecycle, so this adds a real Web Push pipeline:
- New `push_subscriptions` table (one row per browser/device a user has
subscribed from; endpoint is unique so re-subscribing overwrites
rather than accumulating stale rows).
- VAPID keypair config (lib/push/vapid.ts) — reads
VAPID_PUBLIC_KEY/VAPID_PRIVATE_KEY/VAPID_SUBJECT from the environment;
push is silently disabled (never throws) if they're unset, matching
this codebase's existing "an optional integration outage must never
break the core flow" pattern (see the LDAP auth comment).
- public/sw.js: a minimal service worker — `push` -> showNotification,
`notificationclick` -> focus or open the ticket.
- API routes: GET /api/push/vapid-public-key (client needs it to call
pushManager.subscribe), POST/DELETE /api/push/subscribe.
- lib/push/client.ts: registers the service worker and subscribes,
called from the notification bell after granting permission and again
on mount for returning users who already granted it.
- lib/tickets/service.ts: appendMessage() now also fires a push (fire-
and-forget, never awaited by the caller) to every admin plus the
ticket's assignee whenever a *customer* message arrives — same "who
should know" rule as the in-page toast (lib/tickets/visibility.ts).
Failed sends are inspected: a 404/410 (push service no longer
recognizes the subscription) prunes the row; anything else is just
logged, since it might be transient.
Verified server-side end-to-end on this VM: saved a subscription via the
API, created a customer ticket, and confirmed the push attempt actually
fires (web-push validated and rejected a deliberately-malformed test
key, proving the send path is wired correctly) without blocking or
crashing ticket creation. Couldn't verify the full real-browser
subscribe-and-receive path or an actual OS popup from here — this VM has
no desktop/notification service, and headless Chromium's Notification
permission can't be reliably granted in this sandbox (unrelated to the
app code); that last mile needs verifying on a real machine.

Reuses the existing portal-token/SSE mechanism (customers.portalToken,
/api/portal/events) for anonymous widget visitors instead of building a
parallel auth system. Public API: session bootstrap + messages endpoint,
both scoped by a non-secret siteKey with optional origin allowlist.
Embeddable script (public/widget.js) is a small self-contained vanilla JS
file: floating button + iframe kept mounted for a live SSE connection,
with a postMessage bridge for the unread badge. Admin UI at
Settings -> Виджет manages sites and shows the embed snippet.
Also generalized recordTelegramInboundMessage -> recordChatInboundMessage
(channel param) since Telegram and the widget need the identical
find-or-create-open-ticket heuristic.
