Unify the visual front door around ĀML's two policy boundaries

[aruintelligence]

What changed

• Lead the live homepage with AI proposes. The host decides. and an interactive agent action preview.
• Show the exact-rule mismatch as BLOCKED, and the policy-matched destination as APPROVAL REQUIRED with zero callbacks until approval.
• Keep the interface render preview available as a second tab and update the first visitor path to the Action Boundary Lab.
• Support allowlisted ?scenario= deep links in the lab so homepage examples open on their corresponding case.

Verification

• Parsed the homepage HTML and checked both JavaScript files with node --check.
• Will verify the deployed page and both interaction paths after checks and merge.
