Generate batch code does not generate from PO receive line items

• [X] I checked and didn't find a similar issue

Describe the bug*

When on a PO, receive line items (which generates new stock items) does not automatically generate batch codes.

This may be more of a missing feature but validation plugin function generate_batch_code feels incomplete without functionality in POs.

Steps to Reproduce

Using a Inventree server with plugins enabled

1. enable a verification plugin, the sample verification plugin works
2. Go to a PO with unreceived line items
3. Click to receive all line items or receive an individual item
4. Click to add a batch code
5. A code is not auto-generated

Expected behaviour

When a batch code is added to a line item in the receive menu it should autofill the entry with a code generated from the generate_batch_code function.

Deployment Method

• [X] Docker
• [ ] Bare metal

@Elitearcanist thanks for reporting. This will be a slightly tricky one to address, due to the way that default field values / validation is handled, but I'll look into it!

I also noticed that when a new build order is created that it doesn't fill the batch code section. It does however fill in the batch code section when creating a build output. I understand that the build order batch code output serves a different purpose than build output batch codes. Would it be possible to give plugins control over auto generating build order batch codes?

While it is certainly possible technically I do not see any of the core team spending time on it soon if no-one needs it. Feature requests implementation is pretty much driven by use cases by the devs.

@Elitearcanist I have been considering a framework for a more flexible generation on serials / batch codes / IPN - perhaps if you are looking for this you would be willing to sponsor the development of this to give it priority?
