Description

Align the loan transaction Adjust/Reverse actions with the backend adjust command contract: correct which types offer each action, separate the two modes in the list and detail views, and stop re-sending the original external id.

Adds the reopening warning for closed/overpaid loans, translated backend error messages, note and reversal external id fields, and refreshes the loan after the adjustment rewrites it.

Walkthrough

The pull request adds Term Loan adjustment and reversal flows, typed adjustment forms, reopening warnings, shared reversal dialogs, localized labels, transaction eligibility tests, and nested backend error-code translation.

Changes

Loan transaction adjustment and reversal

Layer / File(s) Summary
Adjustment rules and shared payload helpers
src/app/loans/loans-view/*helper.ts, src/app/loans/loans-view/*helper.spec.ts
Defines transaction eligibility, reverse-only types, reopening statuses, reversal dialog fields, and trimmed optional reversal payload values.
Transaction tab actions
src/app/loans/loans-view/transactions-tab/*
Adds Term Loan adjustment and reversal actions while preserving separate Working Capital and write-off flows. Term Loan reversal submits an adjust command with zero amount.
Adjustment form and submission
src/app/loans/loans-view/transactions/edit-transaction/*
Uses typed reactive forms, adds reversal metadata fields, validates adjustable transactions, builds an adjust payload, resets hidden payment fields, and displays reopening warnings.
Transaction detail actions
src/app/loans/loans-view/transactions/view-transaction/*
Applies shared eligibility rules, dedicated undo commands, reversal dialogs, dynamic action labels, centralized navigation, and reopening warnings.
Warnings, routing, and localized labels
src/app/shared/form-dialog/*, src/app/loans/loans-routing.module.ts, src/assets/translations/*
Renders optional dialog warnings, changes the edit breadcrumb to Adjust, and adds adjustment, reversal, error, and reopening translations.
Nested error translation
src/app/core/http/error-handler.interceptor.ts, src/app/core/http/error-handler.interceptor.spec.ts
Resolves nested backend codes through errors. translations, including decoded ArrayBuffer responses, and falls back to nested server messages when no translation exists.

Merge Risk: 🔵 Low · up to d8b4a

Several locales show loan-adjustment errors in English, and Term Loan charge-offs cannot be undone from the transaction list even though the detail view offers that action. These are bounded workflow and localization issues that should be addressed before release where possible.

Use one shared spacing token for both warning margins.

AGENTS.md requires shared SCSS spacing variables instead of explicit pixel values. No spacing variable exists in src/main.scss or src/theme/mifosx-theme.scss. Add one shared 16px token, then replace 16px in both .adjust-warning and .form-dialog-warning; changing only this declaration leaves the same violation in the other warning style.

parseErrorBody to read nested errors from errorBody and resolve domain-rule

🟡 Minor · Handle Term Loan charge-offs in the transactions list. · src/app/loans/loans-view/transactions-tab/transactions-tab.component.ts:527-532

527-532: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Handle Term Loan charge-offs in the transactions list. The list eligibility excludes charge-offs, so it renders no Undo action. If a charge-off reaches the dispatch at transactions-tab.component.ts:527-532, the generic reversal branch handles it instead of dispatching undo-charge-off. Add a Term Loan charge-off branch that uses UNDOCHARGEOFF_LOAN and the dedicated command, matching the transaction detail view.
