if a room has no room topic set, the placeholder 'Room Topic' text in the settings modal is the wrong colour

it should be greyed out, given it's placeholder text, but instead it looks like the real deal, which is very confusing

Locate the settings modal that displays the “Room Topic” text and inspect how its empty-state text is styled. Compare it with the project’s existing placeholder styling, then verify that an unset room topic is visibly greyed out while a real topic remains distinct.
