Verify TC85 against official spec page; soften unconfirmed battery capacity

Cross-checked against tapo.com's TC85 v1 spec page — every field matches
(resolution, sensor, lens, FOV, IR 49ft, IP66, dimensions, weight, codec/fps,
audio, 512GB storage, no RTSP/ONVIF). The stored "10,000mAh" battery capacity
wasn't confirmed on this or any cited source, so replaced with only the
verified charging spec (5V/2A) and battery life (300 days).
