Summary

Fix DTLS 1.2 flight deadline selection so an unarmed retransmission timer takes precedence over an armed connection timeout. This prompts one immediate timeout drive to arm the flight timer, allowing a dropped ClientHello flight to be retransmitted before the overall handshake expires.

Add a regression test that follows only advertised deadlines and document the fix in the changelog.
