When the in-container self-updater downloads a new version, it writes
trigger.json. The new systemd path unit watches for this file and runs
dashcaddy-update.sh, which backs up current API files, copies the new
ones, rebuilds the container, verifies health, and writes result.json.
Automatic rollback on build or health check failure.
Also fixes undefined `isWindows` variable in self-updater.js and adds
DASHCADDY_HOST_UPDATES_DIR env var to the installer's docker-compose
template for correct container-to-host path translation.
