🎨 [#1617] Fixing labels for correct HTML syntax

[jiromaykin]

Labels should not be surrounding other labels = incorrect HTML that also makes some accessibility tests fail.
So this PR attempts to remove unnecessary Label tags while keeping the styling the same.
Also any styling that targets the Label TAG instead of the .label class needs to be either removed or needs the .label class added to it.
CSS Styling for third-party Label tags has not been changed.

(PS: removed the 'Label' file because that one was React only).

extra info: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/label
note "Don't place interactive elements such as anchors or buttons inside a label. Doing so makes it difficult for people to activate the form input associated with the label."

What about search.html 69ff.? Are these nested labels appropriate there?

@pi-sigma those I already fixed in the older PR you still have to review :-D (this one: #709) That's the older PR I worked on first - if that one is okay, then those changes should be merged first and will also improve this new one.
