Update UCP/DTR terminology to MKE/MSR across all references

Mirantis renamed UCP to MKE (Mirantis Kubernetes Engine) and DTR to MSR
(Mirantis Secure Registry). Update question text to include "(now MKE)"
and "(now MSR)" annotations for clarity. Update help URLs from legacy
docs.mirantis.com/docker-enterprise paths to current MKE 3.7 and MSR 2.9
documentation paths. Update README.md links accordingly.

Files updated: 14 YAML files + README.md
