core: frontend: vehicle-setup: motor reversal detection clarity suggestion

[ES-Alexander]

Current behaviour

The status updates are a bit plain, and don't indicate positivity / severity.

Expected or desired behaviour

As suggested in this comment it would be more intuitive for users if the status updates were coloured by type (e.g. --success for steps that work, --warning for bad thrust, and --critical for failure).
