The Visual Editor and Code Editor should throw errors properly or show toast elements when the code is not saved - it currently keeps loading forever and sometimes it states the file is saved (but it's not).

We should also take a look at loading/saving speeds, as it's taking too much time to load/save when the KB is deeply customized or has a lot of revisions from past requests. If this issues comes from the Visual Editor feature, we should separate code from the visual editor.

The VE is spa, and we lack the ability to load specific pages as we did in the previous version, for instance:

We used to have page specific urls: https://academy.helpjuice.com/admin/customize/main_layout

Now we have just a single page for everything: https://testcompanyhelpjuice1000.helpjuice.com/admin/customize/panel
