Fix date range filtering to show all transactions from bill date

Fixed bug where manual receipt mapping was only showing transactions near the due date instead of the full range from bill date to due date + 5 days. The issue was that we were taking only the top 100 most recent transactions before applying merchant relevance sorting, which cut off older transactions near the bill date.

Now the query retrieves ALL transactions within the date range (bill date to due date + 5), then sorts by merchant relevance and date. This ensures bills like electric bills show all transactions from the bill date through the payment date.
