fix: include cameleer3-log-appender.jar in runtime base image

The log appender JAR was missing from the cameleer-runtime-base Docker
image, causing agent log forwarding to silently fail with "No supported
logging framework found, log forwarding disabled". This meant only
container stdout logs (source=container) were captured — no application
or agent logs reached ClickHouse.

CI now downloads the appender JAR from the Maven registry alongside the
agent JAR, and the Dockerfile COPYs it to /app/cameleer3-log-appender.jar
where the server's Docker entrypoint expects it (-Dloader.path for
Spring Boot, -cp for plain Java).
