Description

Automatically refresh the certificate expiry on status pages when enabled.

Fixes #5059

Avoided E2E tests as certificate expiry on status pages are currently marked TODO. I can add api unit tests if needed (though the code is pretty simple and replicated elsewhere).

Can be merged by junior (probably @CommanderStorm since you interacted with the original issue) as there aren't any breaking changes and the changes just match an average user's expected behavior.
