Replace static HTML mockups and WebSocket skeleton demos with the actual
self-contained web components (with built-in demo data) for rcart, rtube,
rfunds, rnotes, rtrips, and rvote — matching the rcal demo pattern.

All 22 module directories under modules/ now match their module IDs
(e.g. modules/cart → modules/rcart, modules/canvas → modules/rspace).
Updated all import paths, vite build config, HTML template asset refs,
docker-compose standalone commands, and .gitignore accordingly.
