AI doesn't get everything right - edit it's outputs

With our mill certificate AI, we do our best to extract information accurately but the low-resolution scan, the signature in Sharpie over a value, and more can make the results incorrect some times. As a result we now give you the ability to make tracked amendments once AI has imported as much as it can from the mill certificates uploaded. This is the first in a line of small features to ensure you have immutable traceability of results.
