Do not show insights charts with DORA4 metrics for unauthorized users

What does this MR do and why?

Removes dashboard charts that contain DORA metrics for users without REPORTER access. In the case of the dashboard having only unauthorized charts(with DORA) it gets removed from the configuration.

The filter is being applied for insights with custom configuration or default configuration on both projects and groups.
