[FEATURE] Create Unified start-silver Script with Pluggable IdP Support #259
Description
Summary
Currently, Silver uses separate startup scripts to run with different Identity Providers (Thunder and Keycloak). This needs to be replaced with a single, unified start-silver script that can start Silver with any Identity Provider based on configuration, allowing IdP-specific logic to be handled in separate files.
Why is this feature needed?
This change is needed to remove tight coupling between Silver and a specific Identity Provider, reduce duplicated startup logic, and make it easy to add or switch Identity Providers in the future without modifying the core startup process.
