Remove invalid size prop from RechartsPortfolioPieChart component

Fixed TypeScript error where size prop was being passed to RechartsPortfolioPieChart
but the component only accepts projects and totalTons props. The component is
responsive by default and doesn't need a size parameter.

This resolves the Docker build error:
Property 'size' does not exist on type 'IntrinsicAttributes & RechartsPortfolioPieChartProps'

Verified with tsc --noEmit that no other TypeScript errors exist.
