🐛(nginx) add page reconciliation on nginx

The nginx conf was lacking the page reconciliation.
It is necessary to have it in place to avoid
404 errors when refreshing the page or accessing
a page directly.
It is a known issue when using the Next Router
in "export" mode, as it relies on client-side routing.
