Introduce a self-cleaning service worker to replace the old one.

Previous attempts (flutter#170918,
flutter#173609) had (accidentally?)
disabled the loading of the service worker in `flutter.js`. This PR
preserves the logic for loading the service worker, and it prints a
deprecation warning.

Towards flutter#156910
Closes flutter#106225

Flutter does not content-hash its build output, so nginx has to send
`Cache-Control: no-cache` for it: every asset is revalidated on each
load. Measured on a warm reload, 56 of 56 requests were conditional and
none was served without a round trip, for 17 KB of actual payload.

The invalidation mechanism this build needs is a path/MD5 manifest
diffed between deploys. Flutter used to ship exactly that as
flutter_service_worker.js and replaced it with a self-unregistering stub
in 3.39 (flutter/flutter#176834), so the logic moves into
web/push_sw.js, whose manifest is generated at build time. Push and
precache share one file because a scope can only be controlled by a
single worker.

index.html stops unregistering service workers on load and registers
this one instead, awaiting it so a first install does not download
main.dart.js twice.

config.json is deliberately excluded from the manifest: it is injected
at deploy time from Helm values, so a build-time hash would pin the app
to a stale homeserver or VAPID key.

* fix(web): serve build assets from a precache service worker

* fix(web): keep failed responses out of the shell cache

onlineFirst cached whatever the network returned for a root navigation,
including error pages. A 500 served during a deploy would have been
stored as the shell and then handed back by the offline fallback, so the
app would start into that error page until the next successful load
replaced it.

The response still reaches the page; it just no longer enters the cache.
