Feature/custom fields default values (#5389)

* Fixes CustomFieldsetsController::fields() which I think is not used anywhere else and don't think ever worked as you can't call get() on a Collection.
Have tested extensively and doesn't seem to affect anywhere else?

* Adds default value functionality

* Adds built assets

* Fixes assignment to asset_model_id which should have been evaluation and alters route so it sits more in line with existing work

* Updates built assets

* Remove silly docker.env file; fix Dockerfile to preserve Oauth keys (#5377)

* Added department to custom asset export
Updates build assets

* Adds translation support for 'add default values' checkbox label
