[KB-8] knowledge_base: ml_experiments_and_monitoring #19

Roadmap ID: KB-8

KB-sized slice of mlops_stacks: experiments, registered_models with aliases, quality_monitors with notifications, and grants.

Acceptance criteria

• Validates standalone
• Monitor refresh schedule + notification
• Grants for a consumer group

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
