front: editor: fixes #6439

Details:
- Adds the required attribute to the composition code input so that it
  is red when empty
- Adds a canSave optional function to rangeEdition/tool-factory, to
  allow disabling the save button when state is not correct
- Uses the new canSave function in SpeedEditionTool to disable the save
  button when there are empty composition codes
