refactor: Centralize Platform information

1. All platform data/metadata are now stored in
   src/app/auth/model/auth-credentials.ts
2. This is a central source of truth from which
   other components, like platform-credentials-modal.component.ts
   can get Platform data like API endpoints, labels etc.
3. This refactor was needed because the existing
   hacky formula for extracting information from
   the API URL breaks with the China setup and
4. It is error prone to add platform information
   in multiple places, for example when F4C was
   added the short and long names were not updated.
   We now use DRY principle and centralize the
   platform list.
5. China platform added to list
