Refresh Creator Rankings

Start a rebuild of one country board, or every supported market.

Returns as soon as the work is scheduled. A single board is a synchronous Apify run that can take minutes, and the full sweep runs them back to back — far longer than the serverless proxy in front of this endpoint will hold a connection open. Waiting inline is what made the admin panel's first attempt fail with a bare "Network error" while the run itself was healthy. Poll GET /admin/rankings/status for progress.

Each board is replaced wholesale — a creator who fell off the leaderboard has to disappear from it — but a fetch that comes back empty leaves the existing board alone rather than blanking a live page.
