fix: workflow blueprints freely editable after creation (preserve_user_graph)

Browse Source 
canonicalize_workflow_config was silently rebuilding any workflow with
ui.blueprint or ui.preset == still_graph from the canonical template on
every save, preflight, and read — making blueprint-based workflows
effectively read-only.

Add preserve_user_graph=True flag that skips the rebuild blocks. Only
create_workflow still uses preserve_user_graph=False so blueprints are
correctly expanded at creation time.
