[FSR] BE support for housing expenses update

[Dr-Pongo]

Issue Description

Just wanted to confirm the BE can support enabling the housing expense feature flag changes before we work on a release plan. Most of the calculation logic is set up on the FE, but wanted to confirm the BE full transforms supports the new data structure.

Feature flag: financial_status_report_expenses_update FE structure changes: Before: data.expenses.expenseRecords (array) After: data.expenses.monthlyHousingExpenses (string)

Note from Derek: We may need backwards compatability in the data we are storing for in progress/submitted forms.\

Look into calculate expenses endpoint

I checked the codebase and can confirm that monthlyHousingExpenses is part of the new expense calculator. It's specifically at modules/debts_api/lib/debts_api/v0/fsr_form_transform/enhanced_expense_calculator.rb:23. It is saved under the rentOrMortgage key in the form's expenses property.

So if you go to the FinancialStatusReportsCalculations controller and hit the all_expenses endpoint, then the monthlyHousingExpenses value will be under the rentOrMortgage property.
