Fix missing web templates and static assets when building with Dockerfile-Web

[vitorvasc]

Summary

• Add COPY instructions for tools/www-tpl and tools/www to Dockerfile-Web.

These directories are required at runtime but were never copied into the container image. Dockerfile-Web only copied the JAR, figuredata.xml, and the entrypoint script, but not the templates (tools/www-tpl/) or static assets (tools/www/) directories. This behavior was causing a container crash on startup, with an infinite recursion:
