feat(ui): fold the Workflows page into Dashboard → Analytics → Workflow

The workflow analytics now render under the Analytics tab's Workflow
sub-tab; ?tab= and ?sub= deep-link the Dashboard, /workflows redirects there,
and the sidebar drops its Workflows item.

Two constraints: no alias may collide with another node's id or alias (`phaseIdx` takes the FIRST match, so a duplicate silently resolves a declaration onto the wrong node), and all aliases of one node share one record slot (`stageRecords` resolves each declared key onto its node, and the canonical id's record wins), so a sub-state that needs its own `--evidence` has to be a real node.
