##Description This PR fixes a potential NullPointerException in calculateEMIOnActualModelWithFlatInterestMethod within ProgressiveEMICalculator. When recalculation starts from the first repayment period, firstRepaymentPeriod.getPrevious() can return empty. In such cases, alreadyRepaidPrincipals becomes null and is later used in a subtraction operation, which may lead to a runtime exception. ##Changes Replaced null fallback with Money.zero(currency) to ensure safe computation Added unit test to validate behavior when no previous repayment period exists ##Impact Prevents runtime failure in flat interest EMI calculation Maintains existing business logic and behavior ##Testing Added test case to ensure no exception is thrown in the identified scenario Verified existing tests pass for the progressive loan module ##Jira: https://issues.apache.org/jira/browse/FINERACT-2552 ## Checklist Please make sure these boxes are checked before submitting your pull request - thanks! - [x] Write the commit message as per [our guidelines](https://github.com/apache/fineract/blob/develop/CONTRIBUTING.md#pull-requests) - [x] Acknowledge that we will not review PRs that are not passing the build _("green")_ - it is your responsibility to get a proposed PR to pass the build, not primarily the project's maintainers. - [x] Create/update [unit or integration tests](https://fineract.apache.org/docs/current/#_testing) for verifying the changes made. - [x] Follow our [coding conventions](https://cwiki.apache.org/confluence/display/FINERACT/Coding+Conventions). - [ ] Add required Swagger annotation and update API documentation at fineract-provider/src/main/resources/static/legacy-docs/apiLive.htm with details of any API changes - [ ] [This PR must not be a "code dump"](https://cwiki.apache.org/confluence/display/FINERACT/Pull+Request+Size+Limit).
