/**
 * TP-Link (Tapo/VIGI) camera integration.
 *
 * TP-Link has NO public cloud API. Tapo cameras support local RTSP +
 * ONVIF. VIGI is enterprise-only with direct NVR access. For
 * BetterFrame: connect to cameras directly via RTSP on the LAN.
 *
 * RTSP format: rtsp://user:pass@camera_ip/stream1 (main)
 *              rtsp://user:pass@camera_ip/stream2 (sub)
 *
 * This provider is essentially a direct-RTSP helper — no cloud relay.
 * All auth on server — kiosk only gets RTSP URLs.
