Build order improvements (#6343)

* Auto-fill project code

When creating a new child build order, copy project code from parent build

* Auto-fill project code for sales orders

* Annotate "building" quantity to BuildLine serializer

- So we know how many units are in production

* Display building quantity in build line table

* Update API version info

* Skeleton for BuildLineTable

- No content yet (needs work)

* Refactor part hovercard

* Navigate to part

* Add actions for build line table

* Display more information for "available stock" column

* More updates

* Fix "building" filter

- Rename to "in_production"

* Add filters

* Remove unused imports
