unable to upgrade PWA

when a new version is available, the app cannot be upgraded from a pwa or mobile browser like brave or FF.

Expose a route /client/version on express server. This route output a simple result :

{"version": "X.Y.Z"}

If when comparing this version value with current one of active client we detect a change, we must start an upgrade process. This update process should not be automatic and displayed to user for validation.

Upgrade process when started must take care of cleaning correctly local cache of previous version

I see 2 scenarios:

1. the release is published while using it
2. the release has been published before the app (re)load

In first scenario we can notify the user that a new version is available (that's why I talk about a notification) and when the user click upgrade, it simply reload the app.

That brings us to the 2nd scenario, in case of a reload, the actual offline tool (that enables PWA) should use the network and clear the cache.
It looks like this doesn't work correctly.
