Merge origin/main into multi-port-service

Resolve conflicts:
- deployment_context.py: Keep single modify_yaml method from main
- fixturenet-optimism/commands.py: Use modify_yaml helper from main
- deployment_create.py: Keep helm-chart, network-dir, initial-peers options
- deploy_webapp.py: Update create_operation call signature
