v1.47.1

• Headless self-update path is no longer silent (#43, @LeeNX). Without Telegram, the Web UI's self-update button runs the auto-selfupdate path — whose failure exits all returned a bare False with zero output, so a failing image pull was indistinguishable from "already up to date". Every exit now prints its reason to the container log (skipped / can't inspect self / pull failed with ref+stderr / up to date / update found), and the button press logs its outcome.
• Startup log states version and debug state (suggested by @LeeNX): Docksentry started. (v1.47.1, debug OFF).
