refactor(hub): drop redundant Full-Mode Mod demo tab; label the collapsed Hub chip

The Full-Mode Mod page overlapped the live Mods tab and only half-worked
unless Full Lua access was enabled on the scope, so it read as a broken
tab. Removed its registration, the page class, and the now-unused source
override field/helper on FullAccessHubDemoController.

Collapsed Hub now shows a 'CoreAI' brand label beside the restore button
instead of a blank dark bar with a lone floating '+'.

Bump to 6.1.1.
