lib.sh: resolve app paths under apps/ instead of repo root

Add APPS_ROOT=$REPO_ROOT/apps and use it in configure_app, start_app, and
start_app_service. All install scripts pick up the change automatically since
they call these functions. DOCKER_DATA_ROOT in install-debian.sh remains at
$REPO_ROOT/docker-lib (adjacent to apps/, not inside it).
