AAU token for ConnectorClient should use Scope from config

[tracyboehrer]

Fixes #679

[Copilot]

Pull Request Overview

This PR modifies the authentication configuration to use a configurable scope instead of a hardcoded production scope for AAU token requests in ConnectorClient. The changes allow the scope to be specified through environment variables and configuration settings.

• Added a configurable scope property to authentication configuration
• Updated token provider to use the configured scope when available, falling back to the default production scope
• Added conditional logic to skip user token client creation for agentic requests
