JOBS-2477: Migrate fluentd sidecar to Echo secure base (Dockerfile only)

+> [!IMPORTANT]
+> The fluentd image runs as a non-root user (`fluent`, uid `999`). The container tails the Artifactory log files from the mounted directory and writes `.pos` (position) files next to them, so uid `999` must be able to **read** the mounted log files and **write** into the mounted log directory. JFrog product logs are typically owned by the product user (for example uid `1030`, directory mode `755`, files mode `640`), which uid `999` cannot access by default - fluentd then fails with `Errno::EACCES ... .pos` and the worker restarts in a loop. To avoid this, either run the container as root (`docker run --user root ...`), run it as the uid that owns the Artifactory logs (`--user <artifactory-uid>`), or make the mounted log directory readable and writable by uid `999`.
