ChartDataSignature class
Stable, content-based signature for chart payload/config data.
This is intentionally independent from Dart object identity/hashCode so it can safely drive memoization, callback de-duping, and diagnostics even when callers rebuild equivalent maps or mutate a reused map instance.
