Give every team member the same box layout, even with no data yet

Peter, Daniel, Niklas, and Aleksandra were showing a single plain text
alert while Mckinley got the full stat-tile/chart/table layout - now
everyone gets the same boxes (stat tiles, chart cards, posts table,
demographics cards), just with "No data yet" placeholders where a
person hasn't submitted an export. Keeps the tab visually consistent
across all five regardless of who has data yet.
