Open rFlows directly into the interactive canvas instead of the landing
page. Adds a full flow storage system (Automerge for authenticated users,
localStorage for demo/anon) with CRUD operations, auto-save with 1.5s
debounce, flow switching via toolbar dropdown, and a management modal
for rename/duplicate/export/import/delete. Viewport state (zoom/pan)
persists per-flow in localStorage.

Update docker-compose, vite config, Traefik labels, module imports,
and all cross-module references to use the new rflows naming.
