Update texts and banners for users with an expired license

[Agathemed]

The messages for users with an expired license need to be updated:

• to inform users about the optimize CSS features that will/have disappear/ed
• to display the correct renewal price

Conditions and messages are available here.

@Agathemed from what I saw in the code we need to add new cases for the licence, am I right?

Just want to confirm before grooming.

I believe the only case that is not in place yet is the "not grand-fathered user" scenario.

@piotrbak look like the API doesn't provides us the information if an user is grand-fathered.

Scope a solution ✅

We need to update all the banners to update the part related to the price + discount that is going to be offered.

In Engine\License\Renewal:

• Update display_renewal_soon_banner() method to check for grandfathered and change the message returned
• Update display_renewal_expired_banner() method to check for grandfathered and change the message returned
• Update the renewal views to display the new message from the variable
• Update the related tests

Estimate the effort ✅
