[Frontend] In-progress checkin: migrating style tags to classes, other

WTD-894
Significant migration of inline styles to CSS classes;
Changed telemetry component so that when title is hidden, telem element can take up 100% of the element width;
Static text elements now show scrollbars on overflow;
Added padding and box-sizing to text elements - this is throwing off the selected control because of the offset and should be fixed;
