Redesign the rounds page from a card-per-competition layout to a flat
pipeline/timeline view. Rounds display as compact rows connected by a
vertical track with status dots (pulsing green for active). Special
awards branch off to the right from their linked evaluation round with
connector lines and tooltip details. Competition settings moved to a
dialog behind a gear icon. Filter pills replace the dropdown selector.
