Add HTTP prober, optimize mDNS timeout, add Trassir/ZOSI to OUI

- Add HTTPProber: parallel HEAD+GET on ports 80/8080, extracts Server header
- Reduce mDNS timeout from 1s to 100ms using context wrapper around
  mdns.Query (HomeKit devices respond in 2-10ms, no need to wait 1s)
- Add Trassir (F0:23:B9) and ZOSI (00:05:FE) to camera OUI database
- Probe response time improved from ~1s to ~110ms for reachable devices
