Move model views out of the dashboard utility bulk

Probability and multi-model view adapters were still embedded in dashboard-utils even though table, panel, modal, and city-card views use them as small pure selectors. This moves them into model-utils and keeps dashboard-utils re-export compatibility.

Constraint: Preserve model/probability return shapes and existing fallback behavior.

Rejected: Merge model-utils with chart-utils | model selectors and chart data preparation change at different rates.

Confidence: high

Scope-risk: narrow

Reversibility: clean

Tested: TypeScript diagnostics for model-utils, dashboard-utils, and PanelSections

Tested: npm run build

Not-tested: Bundle analyzer size comparison.
