BOM / Build Updates (#6604)

* Fix for build line table

- Prefill source location correctly

* Refactor API filtering for BomList

- Make use of RestFilter class

* Add "external stock" field to BomItem serializer

* Simplify custom filtering

* Add "structural" column to part table

* Update BOM tables:

- Display indication of "external stock"

* Annotate "external_stock" to part serializer

- Update PartTable [PUI]

* Annotate BuildLine serializer too

* BuildLine endpoint - filter available stock based on source build order

- If build order is specified, and has a source location, use that to filter available stock!

* Add message above build line table

* Update BuildLineTable

* Bump API version
