[FEATURE] Add Workload Management Group Column to Top Queries Table

[ansjcy]

Is your feature request related to a problem?

Currently, the Query Insights Dashboard doesn't display Workload Management (WLM) group information associated with queries. As the backend is being enhanced to capture and store WLM group data (opensearch-project/query-insights#287), we need to update the dashboard to display and leverage this information.

What solution would you like?

Update the Query Insights Dashboard to incorporate WLM group information with the following changes:

• Add a new "WLM Group" column to the top queries table
• Ensure proper handling of null/undefined values for backwards compatibility with records created before this enhancement, potentially with dynamic table columns.
• Add WLM Group to the available filter and sorting options in the bar

What alternatives have you considered?
