Major Revision

• RestServer - add image regex to limit the valid image

[Copilot]

Pull Request Overview

This PR adds a configurable option to control whether container images must be pulled from Azure Container Registry (ACR). The feature allows administrators to enforce or relax ACR-only image requirements based on deployment needs.

Key changes:

• Added forceAcr configuration option that can be set via environment variable
• Made ACR validation conditional based on the new configuration flag
• Set default value to false for backward compatibility
