Add time stamp for last update to Billing Filter Buttons

The calculated balance amounts displayed on the Amount Unpaid and Amount In Process filter buttons within the Billing section are not updated in real time. This delay has led to confusion and mistrust among hundreds of customers who rely on these figures to monitor parent payment status accurately.

The lack of real-time updates creates a perceived discrepancy in payment processing and undermines confidence in the accuracy of Procare Billing.

To address this, we recommend adding a visible timestamp indicating the last update time for these calculations. This small but transparent improvement can help rebuild user trust by showing when data was last refreshed.
