The previous commit limited --source to auto/esp32/wifi/simulated, which
rejected the vendor names the server already keys on: mediatek, qualcomm,
realtek (RTL8720F radar) and realtek_csi (RTL8721Dx CSI). They are the
labels the UDP receiver writes and effective_source() ages.
On 03a89793 those names fell into the catch-all plan, which bound no UDP
receiver, so vendor frames were never ingested. They now plan like esp32
(UDP receiver bound) without the ESP32-shaped simulator. Anything else,
including case variants and runtime-only labels like "mediatek:simulated",
is still rejected.
