[FIX] point_of_sale: Include uncategorized products in sales report

Prior to this commit, products without assigned categories were not
displayed in the sales details report. This issue was due to the
report's logic excluding products that did not fall under any
specific POS category.

This commit introduces a change where products without categories are
now considered under a default category named "Not Categorized" in the
sales report. This ensures that all products, regardless of category
status, are accounted for and visible in the sales details, improving
the comprehensiveness and accuracy of the report.
