Code insights: link bars of grouping insight type to searches

Created by: vovakulikov

Based on RFC jobs-to-be-done we should support URLs for aggregations bar clicks. This means that we should also support links for compute-powered insight on the dashboard page. Currently, API doesn't have all the needed information to achieve this. After API supports this, we should update the FE part accordingly to support links.

Note: capture group is potentially out of scope for this one. See #29957 for the context.
