When the chart's container grows, the canvas style width/height were not being updated because they were already set (from initial render). This caused the chart to shrink correctly but not grow when the window was enlarged. This fix updates the canvas style width/height during resize when they differ from the current chart dimensions, allowing the chart to properly resize in both directions. Fixes chartjs#12177

Summary
Fixes #12177
When a chart's container grows (e.g., window resize making the container larger), the canvas would not grow to fill the new space. The canvas style dimensions were only set initially but not updated on subsequent resizes.
Changes
retinaScalefunction inhelpers.dom.tsto update the canvas style dimensions during resize if they were previously set by Chart.jsTechnical Details
The fix checks if the current style dimensions differ from the chart dimensions and updates them accordingly. This maintains the behavior where Chart.js-managed styles are kept in sync with the actual chart size.
