(core) Change the label/nickname of the paid plan to Pro

Summary:
This is to match the pricing page, and to reduce confusion. The same
change was made to the description of the corresponding "pricing" object
on Stripe. The Stripe value is what's used in practice; this value is
actually only used as a fallback.

Test Plan: The code change does not affect tests, but several tests fixed after grist-core merge.
