test: repair stale assertions in bluetooth group and deauth detector

Browse Source 
Bluetooth aggregator/api/heuristics tests updated to current behavior;
deauth detector integration test rewritten to exercise the tracker and
alert path directly instead of patching __globals__ (read-only on
Python 3.14).
