fix tcp_proxy deadlock: send CLOSE on TUN FIN + full proxy diagnostics

- proxy_recv_cb(p=NULL): now calls transport->close() to signal exit side
- Add PROXY FIN/CLOSE/CONNECTED/DATA/FEED/TCP_IN/TCP_OUT logs
- Add RP RECV/SEND/CLOSE logs on exit side
- Fix queue_dgram_free/queue_entry_free ordering (UAF) in all proxy files
- Change TRAFFIC logs from ERROR to INFO level
- Add 2 extra 1MB tests in run_test.sh to verify no post-stress stall
- stress_client.py: add --verbose per-thread timing (connect/send/recv ms)
- mem.c: zero freed memory for early UAF detection

fix use-after-free in queue_entry_free/dgram_free ordering + add tcp_proxy stress test + proxy diagnostics logging

- Fix queue_entry_free before queue_dgram_free in all proxy files (UAF bug causing segfault)
- Add PROXY/RP prefixed diagnostic logs for transparent proxy flow tracking
- Add tcp_proxy integration test: real utun instances, ETCP, remote_proxy, DNAT routing
- 7 test scenarios: basic_1mb, concurrent_5, concurrent_20, half_close, idle, conn_refused, stress (10 threads x 20 iterations)
- stress_client.py with --verbose per-thread phase timing (connect/send/recv)
