Subject: [PATCH] fix: restore Block2 retry debug logging dropped during port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Task 8's port of retry/retransmit from localthings dropped the per-attempt
timeout/retry log lines (present in coap_dtls.py) — found while gathering
real-device pacing evidence, where the missing logs made retry frequency
impossible to see. Restores both the retry and final-timeout log lines.
