Send a campaign-page presence heartbeat
POST
/presence/fundraisers/{id}
Records that a visitor has a campaign page open; feeds the "N people viewing" chip in GET /home/activity. Designed for navigator.sendBeacon — no body. The visitor is the visitor_id cookie, or the per-tab v query parameter when there is no cookie; only a one-way hash of it is stored, and it expires on its own.
No authentication. Rate limited at 4 requests/minute per IP and campaign, then the 300/minute public bucket.
