[dashboard-language] Built-in pages: experiments render slice

Milestone

Built-in pages

Specification coverage

• Section 10.2
• DLS-PAGE-007
• DLS-PAGE-014

What shipped

• Rendered the experiments built-in page from declarative built-in definitions in pages/dashboard/src/presenter.js.
• Exposed experiment definitions together with observed run-to-variant assignments, grader observations, eval observations, downstream outcomes, available usage AIC, and operational value by definition.
• Added an explicit non-causation note to preserve the conservative reading required by the specification.
• Added unit and browser coverage for deterministic experiments-page rendering, provenance, and independent availability, completeness, and freshness summaries.
