The pywebpush version bump alone didn't fix WNS: even the latest
release (2.4.0) has no WNS-specific header handling in its own
source, confirmed by inspecting the installed package directly.
Adds the required X-WNS-Cache-Policy header ourselves via
webpush()'s own headers= param, gated to *.notify.windows.com
endpoints.
Also: subscribeToPush()'s permission request and service-worker-ready
wait had no timeout, so a browser that never settles either (seen
live on a fresh Windows/Edge install -- greyed out, no prompt, no
error) left the toggle stuck forever with no feedback. Both now time
out after 20s with an actionable message instead.

WNS (Windows/Edge push) has required an X-WNS-Cache-Policy header
since April 2024; the production venv was likely still on the old
pywebpush 2.0.x installed when the app was first deployed, which
predates the library's fix. Floored the dependency at 2.4.0 (current
latest) so the next deploy picks it up.
Also logs response body and headers on any non-410/404 push failure,
not just body text -- WNS's own 400s carry their actual reason in a
header, which the old body-only logging would still have missed.

Backend: PushSubscription model/migration, VAPID config + `cli.py
generate-vapid-keys`, push_service.send_push_to_user (upsert-by-endpoint
subscribe/unsubscribe, auto-cleanup of expired 404/410 subscriptions),
/api/push/* router, and ConnectionManager now tracks connected user IDs
per room so chat.py can push only to offline members after broadcasting
to online ones.
Two test-infra bugs found and fixed along the way: send_push_to_user
takes the caller's AsyncSession and is awaited inline rather than fired
via asyncio.create_task with its own session (background tasks were
outliving the test event loop); and the ws_client fixture now uses
NullPool to eliminate a connection-pool checkout race that was failing
WS tests intermittently.
Frontend: service worker rebuilt with vite-plugin-pwa's injectManifest
strategy (custom src/sw.ts) so it can add push/notificationclick
handlers alongside the existing precaching and StaleWhileRevalidate
routes ported over from generateSW. New subscribe/unsubscribe flow
(lib/push.ts, api/push.ts) with a toggle in the account menu.
