[KB-11] knowledge_base: unity_catalog_objects #22

Roadmap ID: KB-11

UC catalogs, schemas, volumes with grants, external_locations, and secrets. UC catalogs and secrets are not covered.

Acceptance criteria

• Destroy-order behavior documented
• lifecycle.prevent_destroy on data-holding schemas
• Behavior when the object already exists

Edge-case checklist

• AWS / Azure / GCP support matrix (storage URIs, identity, node types, region availability)
• Serverless vs classic both validated, or the unsupported one documented
• No secrets in templates; use secret scopes / workload identity
• Dev schedules paused; no always-on costly resources in tests
• Re-deploy is idempotent; an interrupted deploy is safe to retry
• Teardown only removes resources the example owns
