Add option to automatically expire direct referrals
Currently, there is functionality to automatically expire referrals that originated in the Community Queue by adjusting the "Community Referral Threshold" in Referral Settings. But this setting does not apply to direct referrals. It would be good to either have this setting apply to direct referrals as well, or have a separate setting for direct referrals. Alternatively, it would be good to have the labels "Community Referral Threshold" and "Inactive Referral Expiration Threshold" adjusted to make it more clear that they are only related to the CQ. Documentation should be updated accordingly.
