Schema Changes:
- Add Account model (Institution, AccountType enum, Last4, Owner, Nickname)
- Add Transfer model for tracking money movement between accounts
- Update Transaction to support both CardId and AccountId (nullable FKs)
- Rename Transaction.CardLast4 → Last4 (works for both cards and accounts)
- Add PaymentMethodLabel computed property to Transaction
- Create EF Core migration: SplitCardsAndAccounts
Data Model Improvements:
- Accounts: Checking, Savings, Other types
- Transfers: Source/Destination accounts, optional link to original transaction
- Transactions can now link to either a Card OR an Account
- Transfer categories excluded from spending reports via TransactionFilters
UI Pages:
- Add Accounts.cshtml - List all bank accounts with transaction counts
- Add EditAccount.cshtml - Create/edit bank accounts
- Add Accounts link to navigation
- Update all references from CardLast4 to Last4
Service Layer Updates:
- Update CardResolutionResult to use nullable CardId and renamed Last4
- Update TransactionKey record to include AccountId
- Update IsDuplicate check to include both CardId and AccountId
- Update all PaymentMethodLabel usage across pages
This architecture allows proper separation of credit cards from bank
accounts and enables tracking of transfers between accounts without
double-counting in spending reports.
