fixed issue with add customers and add item only showing 100 entries, and added a label displaying the number of entries in the grid

Made some minor improvements with the items page and tested everything so that it is ready for deployment.

Added test mode to the top, and added more detailed errors when attempting to connect with quickbooks

We had a lot of unneeded includes so I got rid of them. Also the PDF loading was different for exclusively order list and it wasn't working so I changed it back

changed error handling to say if we couldnt find the item in qb and changed link to QB to also update the item

Made changes to PDF so that it fits PDF to much better and now ship due autofills to mount due in set status
