ReflectiveQosTable maintains a table of QoS flow mappings for reflective QoS.

This module implements 3GPP TS 37.324 reflective QoS feature, which allows UEs to derive uplink QoS flow characteristics from downlink traffic patterns.

The module tracks downlink flows with their associated QFI values and enables dynamic uplink QFI derivation based on learned flow patterns. Flows automatically expire after a configurable timeout period.
