feat(configurator): D1+D2 - drafts dual-routing + legacy deprecation banner

D1: action_open_draft method routes drafts-list click to the matching
form view by view_source. view_source badge column added to the drafts
list (Express=blue, Legacy=muted).

D2: Deprecation banner on the legacy direct-order form pointing operators
to the new Express view, plus a Switch-to-Express header button. Legacy
action context defaults new drafts to view_source='legacy' (Express
action defaults to 'express') so newly-created drafts open in the right
view automatically.
