- The top-bar room-layout button was an icon-only canvas with no label or
tooltip, while the Settings button beside it is labeled — a discoverability
and consistency gap. Wrap it in the existing tooltip pattern ("Room layout",
Position::Bottom) so its purpose is discoverable on hover.
- The Audio Devices input/output columns used spacing(4) while every other
Settings section uses spacing(8); bump both to 8 for an even vertical rhythm.
Pure presentational changes. Build + clippy clean.
