Compare Baseline And Reform Household Calculation

[SakshiKekre]

[CODE IN PROGRESS; NOT READY FOR REVIEW. Depends on #226 for Simulation.output field. To be merged after that]

This PR Implements household calculation comparison display:

• Extract baseline and reform simulation outputs in ReportOutputPage

  • Use positional mapping: simulationIds[0] = baseline, [1] = reform
  • Pass extracted outputs through OverviewSubPage to HouseholdOverview

• Update HouseholdOverview to accept baseline and reform props

  • Add comparison logic to VariableArithmetic component
  • Show "rises by" / "falls by" text when reform exists
  • Show baseline value only when no reform present
  • Filter child variables based on non-zero values in either baseline or reform

• Update title to show comparison summary

  • "increases by $X" / "decreases by $X" when reform exists
  • "is $X" when only baseline exists

Based on v1 app's NetIncomeBreakdown.jsx comparison pattern.
