Pull Request Overview
This PR adds a default target port (8000) for Azure App Service endpoints when no explicit target port is specified in the endpoint configuration. This prevents runtime issues by ensuring App Service resources always have a valid target port configured.
Key Changes:
- Set default target port to 8000 when no target port is specified
- Apply the default to both the main container configuration and endpoint target ports
- Add test verification to ensure the default port is correctly applied
