Use cached rolled up weights
What does this MR do and why?
This change introduces a performance optimization for calculating work item weights. Previously, the system would always calculate rolled-up weights (totals from child items) by querying the database each time. Now, there's a new feature (behind a feature flag) that allows the system to use pre-calculated cached weight values instead of computing them on-demand.

How to set up and validate locally
