Image Probe

Force-generate ONE character image of a chosen probe type to test the visual setup. Probe types: identity_selfie, full_body_identity, wardrobe_variation, accessory_carry_forward, same_scene_followup, prop_usage, forbidden_visual_check. Runs the same engine the runtime uses (policy cap bypass only). Requires an active identity asset and an open sandbox ``session_id`` for this character; the generated image arrives async as an ``image.ready`` event on that session and the probe report (``GET .../image-probe/{probe_id}``) shows the URL, assets sent, and consistency. Costs one image generation (metered + budget-capped). App-scoped; 404 if not owned.
