<!-- Add the related story/sub-task/bug number, like Resolves #123, or remove if NA --> **Related issue:** Resolves #39304 (part of #25080) Implemented similar approach to https://github.com/fleetdm/fleet/pull/39302, with the difference that the list policies endpoint does not include a count, and there is a separate endpoint. I extended the count policies endpoint to include an `inherited_policy_count`. # Checklist for submitter - [x] Changes file added for user-visible changes in `changes/`, `orbit/changes/` or `ee/fleetd-chrome/changes`.
