All module components were matching URL paths without the 'r' prefix
(e.g., /notes instead of /rnotes), causing API calls to fail when
modules are mounted at /:space/:moduleId. Also adds space attribute
fallback for canvas-embedded usage.

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.
