Pull Request Overview

This PR removes usage of non-production regions in observability by consolidating dev, test, and preprod environments to use the production domain (api.powerplatform.com) instead of their previously dedicated subdomains.

• Removes non-production observability scopes (TEST and PREPROD)
• Updates API host name suffixes for dev/test/preprod to use production domain
• Simplifies getObservabilityAuthenticationScope() to always return production scope
• Updates all related test expectations to reflect the new domain mapping
