_Kerman e01c1a4b41 fix(bundle): mount the projection cache in the web-app overlay 
The cache now opens its domain through ctx.storageDomain, which the
web-app overlay provides (storage-json + storage-domain, backend json).
A parent layer cannot see a child layer's services, so the base-layer
mount from the file-root design is reverted: the cache mount moves back
to web-app next to its storage dependencies, and Config.root is gone.
