* Object-detection proxy for the RunPod YOLO construction-material classifier (#1).
* The key + endpoint URL stay server-side. The client calls this only when
* NEXT_PUBLIC_APG_RUNPOD_DETECT is on; otherwise detection runs fully in-browser
* (COCO-SSD) with no server round-trip. Returns the SDK's DetectedObject[] shape
* (box as 0..1 fractions) so it drops straight into the Objects browser / smart
* albums / search.
*
* POST { imageBase64, width, height } -> { objects: [{ label, confidence, box }] }
* Auth: session-gated (see lib/server/session.ts). Rate limit: 30/min.
