fix: Make native the default saf auth provider

[taban03]

Description

Set native as default SAF Resource Check Provider in the start.sh . It is the first choice fallback in case the property is empty.
This specifically fix the case when no provider is set, and endpoint.enabled is set to true. Old behavior would choose the endpoint as provider. New one will rather fallback on native
