[FIX] web: fixed word breaking in pie chart tooltip of graph view

Currently, words are not breaking properly when reaching at the
end of a line in the pie chart tooltip. It happens because of the
'word-break: break-all;' property used in the o_tooltip_legend class.
and this property breaks the words at any character to prevent overflows.

So this commit fixes the issue by removing the word-break property
so that the CSS automatically applies the default line break rules.
