feat: add code-executor, function-executor, request-port inspectors and enhanced workflow settings

- Create CodeExecutorInspector with implementation directive editor,
  input/output type fields, and directive help callout
- Create FunctionExecutorInspector with built-in function selector
  and key-value parameter editor
- Create RequestPortInspector with port ID, request/response type
  fields, prompt editor, and info callout
- Wire all three inspectors into WorkflowGraphInspector routing,
  keeping PlaceholderNodeInspector as fallback for unknown kinds
- Enhance WorkflowSettingsPanel with OpenTelemetry and sensitive
  data filtering toggles, and a state scopes editor with initial
  values support
