fix: improve error logging for product frontend view

This commit expands on the error handling mechanism in our product model to be more specific during
logging. If a product is activated in the system but not found in the frontend (HTTP 404 response),
an error message is now logged using a 'products_not_found' tag. This will make it easier to
identify and address issues with deactivated products that should be active. This commonly occurs
when an outdated link through a search engine directs a user to a non-existing product page.
