fix: Update Dockerfile for Quarkus 3.x format (quarkus-app)

Quarkus 3.x changed the packaging format from uber-jar (*-runner.jar)
to a multi-file quarkus-app directory structure.

Changes:
- Copy quarkus-app/lib/, app/, quarkus/ directories
- Use quarkus-run.jar as entrypoint instead of app.jar
- Maintains same runtime configuration and health checks

Fixes Docker build compatibility with Quarkus 3.15.1
