* Reformatted the `resources` block for the `openwebui` group to a multi-line format to resolve an illegal semicolon syntax issue.
* Added explicit comments to both `openwebui` and `lobechat` groups to clarify the host pinning constraint.
* Streamlined comments in the `lobechat` group's `resources` block to concisely state the memory allocation, removing outdated "fix" comments and adding a current "FIXED" comment.
These changes enhance the readability, maintainability, and correctness of the Nomad job definition.
