Refactor balance sheet weight calculation and improve group weight rendering

- Update BalanceSheet model to directly calculate account weights based on converted balances.
- Modify dashboard view to compute account weight as a percentage of classification total, enhancing clarity.
- Adjust group weight partial to handle effective weight, ensuring accurate rendering of weight representation.
