[IMP] website_sale_aplicoop: signal frontend to reload on deploy

When we ship a JS-only fix, users with a long-lived tab keep running
the old code until they hard-refresh — there is no clean way to push
new code to an already-loaded page. Now /eskaera/check-status returns
the module's installed_version as client_version, and the eskaera
page embeds the same version in data-build-version on the cart
container. The JS captures the page's build version at init; on every
check-status response it compares them and triggers window.location.
reload() on mismatch. A sessionStorage timestamp guards against
reload loops if the versions stay disagreeing (cached HTML upstream).

The version bump in __manifest__.py also invalidates the asset bundle
URL hash, so even users without this signalling path get fresh JS on
their next navigation.

This is forward-looking: clients on the old JS (no check) still need
one manual refresh today, but every future deploy will auto-recover.
