Subject: [PATCH] Add RTLSDR-Airband Docker deployment config

docker-compose.yml runs ghcr.io/rtl-airband/rtlsdr-airband:latest with
USB passthrough and recording volume mount. rtl_airband.conf monitors
3 EU CB channels (CH3, CH7, CH10) with NFM, bandwidth=8000, correction=-1,
split_on_transmission, and dated subdirectories.
