Categories are the taxonomy both services and resources select from, but
until now they could only be reached through the service catalog, so every
environment ended up with its own spelling of "whole body".
- Settings > Categories page: global CRUD plus the "includes" edge
- POST/GET/DELETE /api/v1/service-category/{uuid}/includes — a DAG, kept
separate from `parent` because "hand" sits under both "whole body" and
"upper limb"; a cycle is refused with 422
- PUT /api/v1/resource/{uuid}/categories — full replacement, and a category
from another environment is rejected explicitly since the uuid arrives in
the request body where TenantFilter does not reach
