Fix some issues to improve the print output

[vekunz]

I fixed some issues with the print output that some elements were not hidden in print mode.

In addition to the issues, I fixed there is another issue, I could not fix. In print mode, the border around the portions selector should disappear. Currently, this is not possible, because in tandoor.min.css on line 10444 is this style, and the !important makes it impossible, to override this from inside a component (because the CSS selector is very strong):

textarea, input:not([type="submit"]):not([class="multiselect__input"]):not([class="select2-search__field"]):not([class="vue-treeselect__input"]), select  {
    background-color: white !important;
    border-radius: .25rem !important;
    border: 1px solid #ced4da !important;
}

Since I do not know what the overall effect of removing the !important is, I left it there.

This is my first contribution and I hope that I have done it properly.

Thank you very much for the contribution and well structured comments.

@Kaibu do you know if the important is required?
