W-23976625: Add Anypoint Clouds how-tos and move deploy/configure off Hyperforce

[kevintroller]

Summary

• Adds an Anypoint Clouds component (US, EU, Canada, Japan, India, Australia) that replaces the EU Control Plane how-tos: Overview, Accessing Anypoint Clouds, Configuring Mule to Access Anypoint Clouds, Deploying Mule Apps, and Finding Endpoints and Allowlists.
• Moves Hyperforce “Deploy Mule Apps to Control Planes” and configure-mule-hyperforce.adoc into that set. Hyperforce keeps feature matrices, control plane region status, and Mule version compatibility.
• Deploying Mule Apps is a routing page (CloudHub 2.0, CloudHub on US/EU only, Runtime Fabric, Hybrid Standalone), not a second product how-to. Old EU and Hyperforce URLs are page-aliases.

Test plan

• Preview Anypoint Clouds Overview: six-cloud URL table, isolation rule, EU residency subsection, xrefs to Hosting Options, Hyperforce, Object Store, Gov Cloud, and PCE.
• Confirm Accessing, Configuring Mule, Deploying Mule Apps, and Finding Endpoints and Allowlists match the sidebar titles (Overview + gerunds).
• Confirm Hyperforce no longer has the deploy section or Configure Mule nav item, and See Also points at Anypoint Clouds.
• Confirm Hosting Options Canada/Japan/India/Australia rows xref Deploying Mule Apps, and CloudHub 2.0 architecture xrefs Anypoint Clouds instead of EU Control Plane.
• After playbook adds anypoint-clouds to docs-hosting start_paths and replaces eu-control-plane in the Hosting nav, confirm old EU URLs alias onto the new pages.
