ImportMyData (SQLite), ImportTransactionCsv, TransactionMatching sections.
Branded BankTransaction/Bill/Category flow through the matching workbench;
relaxed BillModal initialBill to Partial<Bill> (it's a pre-filled draft).
TypeScript caught a real bug: ImportTransactionCsvSection used <CountPill> 6×
but never imported it — a ReferenceError that crashed the CSV preview/results
views. Added the missing import.
