* [management,signal] Make the Let's Encrypt challenge listener address configurable With Let's Encrypt enabled and --port set to something other than 443, signal and management also opened a separate challenge listener that was hard-coded to :443. Non-root deployments, such as the UBI images, could not start that listener. Add --letsencrypt-listen-address to both. It defaults to :443, so current behavior is unchanged. An empty value disables the separate listener for setups that forward public port 443 to --port, where the main TLS listener already answers TLS-ALPN-01 challenges. Signal now fails on startup when the challenge listener cannot bind, and exits non-zero when a server stops unexpectedly instead of exiting 0. A failure reported before the run loop waited was previously dropped. Management no longer opens a new :443 listener on shutdown just to close it. * [management,signal] Keep the challenge listener change additive Remove the Signal fail-fast changes from this PR. They change the behavior that existing installations see after an upgrade, so they move to a separate PR. If the challenge listener cannot bind, Signal now logs the error and continues. The main TLS listener still answers TLS-ALPN-01 challenges. Management keeps its previous behavior and stops with an error. The check for an empty address moves to the caller, so the function does not return a nil listener with a nil error. Also add assertion messages, guard a nil listener in a test cleanup, and add the flag to the Signal README.
