Echo (TG 9990-9999) must be point-to-point: only the originating hotspot
receives the playback. Two bugs in the inject-only proxy broke this:
Data plane (udp_hbp.py): _peer_should_receive_dmrd had a fuzzy-match
fallback (peer_id // 100 == rf_src) for special TGs that leaked the
first VHEAD to every hotspot sharing the user's DMR-id prefix. Removed
the fallback so echo delivers only to the exact RX_PEER.
Report plane (monitor_topology.py): _echo_tx_target_peer resolved the
monitor chip peer via fuzzy rf_src matching, which picked the wrong
hotspot when a user has several radios sharing a base id (e.g. rf_src
7140023 matched peer 714002301 instead of the real originator
714000103). Now resolves from STATUS[slot].RX_PEER when available.
