CHORE: Refactor Backend ENV configuration

[zacktraczyk]

Configuration for backend parameters has been done using firebase secrets which is not supported in gen2 of firebase functions. Runtime environment configuration should be refactored to use parametrized configuration instead.

Below is are old .runtimeconfig.json it should be refactored to a .env that is imported using parameterized configuration:
