fix(adsb): use actual device index for ACARS/VDL2 SDR conflict checks

ACARS and VDL2 conflict warnings were hardcoded to check device === '0'
instead of comparing against the actual ADS-B device (adsbActiveDevice).
This caused false warnings when ADS-B used a different device index.

Also removes hardcoded device-1 defaults for ACARS/VDL2 selectors —
users should pick their own device based on their antenna setup.

Adds profiles: [basic] to the intercept service in docker-compose so it
doesn't port-conflict with intercept-history when using --profile history.
