CVE-2026-71264: Missing authorization vulnerability

WLED's GET /json/cfg endpoint (registered in wled00/wled_server.cpp) calls serveJson with no settings-PIN check, unlike the /edit endpoint which explicitly checks correctPIN, disclosing the device's general configuration (network, hardware, LED setup) to any unauthenticated client on the network.
