It was confusing to label the directory for pages related to the Python
framework "Backend" as, in Odoo, the backend is the web client, and the
frontend is the portal/website. It also led to the "Standard modules"
directory to be placed within the "Backend" directory as of `saas-15.1`
to indicate that they were part of the backend too, but that was a
mistake. Indeed, most standard modules comprise JavaScript methods, and
we could want to document these in the reference at some point.
