Delete branch "copilot/remove-duplicate-data-fetch-paths"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Addresses 10 tech debt items identified across the finance service layer: three data-consistency bugs (mortgage data showing wrong date windows / wrong interest values / hard-deleting records that should be deactivated) and seven DRY/maintenance violations where the same logic existed in multiple places with no shared source of truth.
Description
🔴 Data Consistency Fixes
LedgerApiController::getMortgagePaymentsForMonth— replaced rawCarbon::create()date range withDateRangeService::forMonth()so mortgage data respects user date-cycle settings (matches all other expense categories). Replaced$mortgage->interest_ratedirect field access withMortgageService::calculateMonthlyInterest()which reads thecurrent_interest_raterelation.MortgageService::calculateMonthlyInterest(Mortgage): floatadded as single source of truth;calculateMonthlyPayment()now delegates to it; bothLedgerServiceinline calculations updated.TransactionController::destroynow routes throughTransactionService::destroy()(smart deactivate-vs-delete) instead of calling$transaction->delete()directly. Removed deaddestroyInertia()method which was never wired to a route.🟡 Eliminated Duplication
TransactionService::convertVirtualTransaction(string $virtualId, array $validated, User $user): array— extracted 60-line virtual→real transaction conversion logic shared identically byTransactionControllerandLedgerApiController.BalanceService::calculateSingleMonthBalance()private method — eliminates ~100-line duplication betweengetMonthBalance()andcalculateYearBalance(). Formula changes now require a single edit.TransactionController::combinedLedgerIndex— delegates toDateRangeService::getActiveMonth()instead of re-implementing date-cycle arithmetic.LedgerService::combineMortgageLineItems(Collection): Collection— mortgage Principal+Interest grouping extracted fromDashboardController::getLedgers()into the service layer where all ledger consumers can use it.BalanceService::getDetailedMonthlyBalance— replaced three directwhereHasmodel queries withMortgageService::getActualizedMortgagePaymentsForPeriod(),CreditService::getPaymentsDueForPeriod(), and newCreditService::getCreditCardStatementsDueForPeriod().TransactionService::resolveOrCreateCategory(mixed, TransactionType|string, User): int— category resolution (numeric ID / string name / Vuetify array object) extracted from bothTransactionControllerandLedgerApiController; accepts bothTransactionTypeenum and plain string for the type parameter.TransactionPageController::applyCategorySort()private helper — shared byupdateCategoryOrderandupdateCategoryOrderAjax.🟢 Code Quality

Additional Notes
All changes are purely additive or behaviorally equivalent refactors except the three data-consistency bug fixes. No frontend changes. No migrations.
The
strict_types=1additions exposed several pre-existing implicit type coercions (enum→string, int→bool, decimal-string→float) that PHP was silently handling before. These have all been corrected explicitly at their call sites.Comment

id) is provided, this method returns it without verifying it belongs to the given$userand matches the requested$type. This is a regression for API paths that previously constrained the category lookup (e.g.,createOneTime) and can allow cross-user category assignment if an attacker submits another user's category ID. Fix by resolving IDs through a scoped query (user_id + type) and failing if not found; apply the same rule for the['id' => ...]path. Also consider trimming/normalizing string names beforefirstOrCreateto avoid creating whitespace-variant categories.app/Services/Finance/LedgerService.php:1
