feat(ops): add ops-hub service inventory now view (CUST-WP-0047)

Seed a non-secret service inventory (environments, hosts, clusters,
services, endpoints, access paths, evidence, gaps) with a JSON schema,
a renderer, and a generated service-catalog view. Adds the
`make ops-inventory-view` target, probe ActivityDefinition, and docs.
