The team breakdown page rendered a 5-column table that overflowed on
phones, forcing horizontal scroll. Add a responsive card layout for
mobile that shows every field (pick #, sport, participant, position,
points) with no horizontal scroll, while keeping the existing sortable
table on desktop (md+).
- Header now stacks on mobile (flex-col -> sm:flex-row).
- Mobile renders one card per pick with a compact sort control (field
select + asc/desc toggle) instead of clickable column headers.
- Extract shared PositionCell / PointsValue / pickLabel helpers so the
table and cards stay in sync.
- Update tests to scope table assertions and cover the mobile view.
