Settings (log level, engine level, payload capture, metrics) now
display as color-coded badges by default. Clicking the pencil icon
enters edit mode where badges become dropdowns. Save (checkmark)
persists changes and reverts to badge view; cancel discards changes.
Applied consistently on both the admin App Config page and the
AgentHealth config bar.
