Align BudgetVsActualTable on the income-statement gold standard already
shipped for the real-vs-real compare report (#253/#256): flip TYPE_ORDER
to income-first (revenue -> expense -> transfer) and replace the flat
"Total" row with interleaved Result before transfers / Net result lines.
Roll-up logic extracted into a new pure, tested module
(budgetVsActualResults.ts) mirroring compareResults.ts, with one sign
difference: BVA amounts already arrive signed the accounting way
(expense actual/budget are negative), so the operating result is a
straight add of income + expense rather than a subtraction.
