Adds ApiModeConfig class with support for selecting API transport mode:
- ApiMode enum (http, grpc)
- Static configurations: development (HTTP), developmentGrpc, production, productionGrpc
- fallbackToHttpOnError option for graceful degradation
Creates unified deliveryRoutesProvider and deliveriesProvider that:
- Respect apiModeConfigProvider for transport selection
- Automatically delegate to gRPC or HTTP providers
- Fall back to HTTP on gRPC failures when configured
To enable gRPC, override apiModeConfigProvider with ApiModeConfig.developmentGrpc
in the ProviderScope.
