- Remove min={0} from NumberInput to allow negative actuals (refunds/corrections)
- Fix post() in journal-entries service: use id param directly instead of
RETURNING result which returns [rows, count] in TypeORM QueryRunner
- Handle negative amounts in saveActuals(): negative expense credits the
expense account, negative income debits the income account
