feat(app): enable click action for gauge widgets

[alfredo1996]

Summary

• Extends the existing click-action system to include gauge widgets (scope limited to gauge per user request — single-value is explicitly excluded).
• Sets supportsClickAction: true in the gauge entry of chart-registry.ts.
• Wires onClick={handleEChartsClick} through chart-renderer.tsx so the gauge's BaseChart receives ECharts click events.
• Updates the chart-registry unit test to reflect the new behavior.

Closes #152

Test plan

• app/src/lib/__tests__/chart-registry.test.ts updated — 271 tests pass
• Manual: configure a click action on a gauge widget, click the gauge, confirm the single value row is dispatched as expected

Summary by CodeRabbit

• New Features
  • Gauge charts now support click interactions, allowing users to interact with and trigger actions from gauge visualizations.

Walkthrough

These changes enable click action support for gauge charts by updating the chart registry configuration to mark gauge as supporting click actions, wiring the click handler in the chart renderer component, and updating the corresponding test expectations.
