The backend gate is now per-action, so a single canUpdate driving add, edit and
delete would show buttons the server answers 403 to. Each button now checks its
own action, and the includes modal takes canCreate/canDelete so its add select
and per-edge remove button follow the same split.
ServiceCategoryTab is deliberately left alone: its save patches
/api/v1/service-item/{uuid}, which is ClinicServiceController and already gated on
services.update, so canEdit was already the right permission. Only its read of the
category tree moved behind services.view, and the page it lives on already
requires that.
The page test now drives a configurable can(), covering view-only, create-only,
update-only and delete-only.
