Code Review

This pull request successfully retires the GenUiConfiguration, which simplifies the API by removing the conditional enabling of create, update, and delete actions. The changes are consistently applied throughout the codebase, including the removal of the configuration file, updates to GenUiManager and associated tools, and cleanup of test files. This is a positive simplification of the code. I have one minor formatting suggestion to ensure consistency.

There's an extra blank line in this list initialization. Running the auto-formatter will resolve this and ensure consistency with the project's coding style.

	final List<AiTool<JsonMap>> availableTools = [
	if (configuration.actions.allowCreate ||
	configuration.actions.allowUpdate) ...[
	SurfaceUpdateTool(
	handleMessage: _a2uiMessageController.add,
	catalog: catalog,
	configuration: configuration,
	),
	BeginRenderingTool(
	handleMessage: _a2uiMessageController.add,
	catalogId: catalog.catalogId,

	DeleteSurfaceTool(handleMessage: _a2uiMessageController.add),
	SurfaceUpdateTool(
	handleMessage: _a2uiMessageController.add,
	catalog: catalog,
	),
	BeginRenderingTool(
	handleMessage: _a2uiMessageController.add,
	catalogId: catalog.catalogId,
	),
	DeleteSurfaceTool(handleMessage: _a2uiMessageController.add),
	...additionalTools,

1. The repository style guide states that code should follow relevant style guides and use the correct auto-formatter. In this case, dart format would remove the unnecessary blank line. ^(link)
