URLModificationMiddleware resolves named-URL lookups
against unfiltered Model.objects before RBAC. The 403→404
shim only rewrites 403 responses, leaving the pk=0 miss
path with a different 404 detail string. Differential
"Not found." vs "No <Model> matches..." reveals whether
a named resource (org, credential, inventory, host) exists
anywhere on the platform. Enables cross-tenant internal
hostname enumeration.
