Subgraph/workflow breadcrumbs menu updates (#7852)

## Summary
For users who don't use subgraphs, the workflow name in the top left can
be unnecessarily obstructive so this updated collapses it to a simple
icon until a subgraph is entered.

## Changes

- Add menu button to WorkflowTab for quick workflow actions
- Add menu and back button to SubgraphBreadcrumb
- Extract shared menu items to useBreadcrumbMenu composable
- Add Comfy.RenameWorkflow command for renaming persisted workflows
- Menu always shows root workflow menu, even when in subgraph
