fix(editor/ied): fixed styling how DA(I) values are displayed. (openscd#872)

* 823 Added css styling to the da-container getValue() method.
This breaks the text onto a new line if the text is too long. if there are multiple words, it tries to break it into logic pieces.
* 823 Moved the css to the H4 element
