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
Fixes interface auto-detection failures on Pi Zero 2W where wlan0 doesn't exist
at boot. Implementation:
- Added detect_interface_with_retry() function with 3x retry fallback chain
- Config-supplied interface preferred, then /proc/net/route, then UP interface
- Exponential backoff: 5s, 10s, 20s delays between retries
- Filters excluded prefixes: lo, tailscale*, wg*, tun*, docker*, veth*, br-*
- Used in Engine.__init__(), PacketCapture.start(), MacManager.start()
- Full test coverage: 10 tests for detection, backoff, filtering
Addresses issue where network stack initializes after boot and interfaces
become available after 5-10 second delay.
