[IDEA] Provide code-first only/hybrid configuration

[AndyBoot]

While appsettings.json is excellent for configuration management, it can sometimes introduce unnecessary complexity.

A more streamlined solution could be a code-first approach, where all standard configurations are hard-coded during application startup. In this model, appsettings.json serves as a secondary layer, allowing for environment-specific overrides and additional configurations, such as environment lists. This approach balances the simplicity of code-based configurations with the flexibility of environment-based adjustments.
