fix(update): ensure image tag is specified to prevent pulling all tags

Browse Source 
When Config.Image has no tag (e.g., "nitnelave/lldap" instead of
"nitnelave/lldap:latest"), Docker's API pulls ALL tags for that image.
This caused massive downloads and rate limit hits.

Now appends ":latest" if no tag or digest is present in the image name.
