HU attributes shall be readonly if the HUStatus is not planning

[teosarca]

What is the current behavior?

HU attributes are editable even if the HU editor is Active or something else.

Which are the steps to reproduce?

• select a manufacturing order: https://w101.metasfresh.com:8443/window/53009
• receive an HU => remark that the HUStatus is planning and attributes are editable
• run Process plan quick action
• remark that the HU is active but attributes are editable => NOK

What is the expected or desired behavior?

Attributes shall be readonly if HUStatus is not Planning.

NOTE: atm I decided to apply this rule wherever the HU editor is involved (atm only in receipt candidates and manufacturing order). When we will need to edit the attributes for Active HUs too, we would improve the feature.

Required for #269
