Subject: [PATCH] fix(backend): switch base image from alpine to debian for
 bash compatibility

mvnw is a bash script; eclipse-temurin:21-jdk-alpine only provides ash
(busybox), causing the container to exit silently with code 0 before the
JVM starts. The Debian-based eclipse-temurin:21-jdk image includes bash.
