Premium Content Block: User can't access premium content on renewal date.

[rcrdortiz]

Fixes #46242

Changes proposed in this Pull Request:

• Since we can't guarantee that the subscription renewal will happen exactly at the time of the expiry of the subscription, we now add a one-day grace period to the check that determines if the user can or can't view the premium content.
