fix(demo): boot to dashboard, sample-data notice, robust mobile editor icon (#464)

The demo signs in as an admin on load (no login/change-password screen; /login and /change-password bounce to the dashboard), authEnabled stays true so the People/Teams/Roles/Security settings tabs remain available, the banner notes the admin data is sample data, and the mobile editor icon is an inline SVG so it always renders.

+ * has no external-asset dependency. It previously used a CSS mask over
+ * /edit-image.png, which rendered as nothing whenever that asset failed to load
+ * (e.g. it was missing from the demo build), leaving the icon invisible.
