Messaging on key metrics panel

## Bug Description

I noticed on edge case. That said, it might not be relevant in the future with the SFR rollout but it could impact existing sites.
But here's the deal:
- On a site without SFR, I connect analytics and the Key metric tiles
- The key metric section appears in settings
- I disconnect the analytics module
- On the dashboard, the key metrics section will have the 'change metrics' CTA which will state that user can change their personalised goals or deactivate widget in settings.
- Clicking on the 'Settings' hyperlink leads to settings but there is no Key metrics section there
By right it should be there if we are directing user there. Unless we'd need to hide the 'Change metrics' CTA then.

Start by reproducing the dashboard and settings sequence described: connect analytics, configure Key metrics, disconnect analytics, then follow the “change metrics” CTA’s Settings link. Inspect the Key metrics panel and settings entry points to determine whether the link should expose the section or the CTA should be hidden; done means the resulting navigation and available controls are consistent.
