feat: exclude TRACE packets from logging in RepeaterHandler and PacketRouter

- Updated record_packet_only method to skip logging for TRACE packets, as TraceHelper manages trace paths.
- Enhanced documentation to clarify the handling of TRACE packets in the web UI.
- Added tests to ensure TRACE packets are not recorded, maintaining data integrity.
