Pull Request Overview

This PR adds support for portLevelSettings to the ApisixUpstream CRD, allowing different upstream configurations to be applied based on the service port being accessed. This enables more granular control over upstream behavior such as different schemes (HTTP/HTTPS) or host headers per port.

• Refactored upstream translation to accept port parameter and apply port-specific configurations
• Added comprehensive test coverage for port-level settings functionality
• Updated test infrastructure to support SSL/TLS testing
