Fix transaction delete type mismatch

The `onDelete` prop in `TransactionCard` and `RecentTransactionsSection` components was expecting a function that returns a boolean or a Promise resolving to a boolean, but was receiving a function that returns void. This commit updates the type definition and implementation to ensure the `onDelete` function returns the expected type.
