Strip OPSEC tool identity fingerprints

Replace all sensor.* logger namespaces with __name__ (generic module
identifiers instead of discoverable 'sensor.*' prefixes).

Change hardcoded 'bb' API user to 'admin' in config and code defaults.

Change hardcoded relay_user 'bb' to 'operator' — prevents network
profiling from exposing tool identity via SSH config.

Fixes #457, #458, #459
