The 7 BillModal sub-components + transactionDisplay helper: TemplateSection,
AutopayTrustIndicator, PaymentFormFields, PaymentHistoryList, DebtDetailsSection,
LinkedTransactionsSection, UnmatchDialogs. New @/types.BankTransaction — raw bank
amounts stay in CENTS on the wire, so branded `Cents` (formatCentsUSD, not
formatUSD), the complement to the Dollars brand. BulkUnmatchState typed with
null-safe setState callbacks. typecheck 0, lint 0 errors, build green.

First BillModal decompose step: the collapsible Debt/Snowball fields (interest
rate, current balance, minimum payment, snowball visibility) move to
client/components/bill-modal/DebtDetailsSection.jsx as a presentational
component; state stays in the parent (the save action reads it). Behavior-
preserving — BillModal 1723 -> 1637 lines; build + client tests green.
