## What kind of change does this PR introduce?
Fixes FE-2526.
Adds a global Feature Preview badge to pages enabled via Feature
Previews, improving visibility and making it clearer to users that the
feature can be managed (or disabled) from the Feature Previews settings.
## Why
Previously, once a feature preview was enabled, there was no clear
indication within the UI that:
- the feature was still in preview, or
- where to go to disable it
This lead to confusion and made the feature feel “permanent”.
## What’s included
New FeaturePreviewBadge UI component
