* Remove gRPC and convert PricingClient to HttpClient wrapper

Many instances of StaticStore use are just to get the ProductTierType of a PlanType, but this can be derived from the PlanType itself without having to fetch the entire plan.

* Deprecate StaticStore entry points

* Refactor: Rename some methods and models for consistency
This commit contains no logic changes at all. It's entirely comprised of renames of existing models and methods to bring our codebase more in line with our app's functionality and terminology.
* Add feature flag: AC-2476-deprecate-stripe-sources-api
* Standardize error responses from applicable billing controllers
During my work on CB, I found that just using the built-in TypedResults errors results in the client choking on the response because it's looking for the ErrroResponseModel. The new BaseBillingController provides Error utilities to return TypedResults wrapping that model so the client can process it.
* Add feature flagged payment method endoints to OrganizationBillingController
* Run dotnet format
