Open questions / notes:

• 4,99€/month => Should "month" be hardcoded?
• Will price and hasPlus be loaded independently? (If so we can't use a catch-all "loading" attribute.)
• Can the fallback price for web really be loaded via RemoteConfig regarding our "load values for next app launch" approach? (#697)

4,99€/month => Should "month" be hardcoded?

We can add to the fallback value a suffix like _month. It's likely that we only have per month or per year version.
