fix(editor): use overflow-wrap instead of word-break for text wrapping

word-break: break-all breaks text at any character, causing mid-word
breaks even when the word could fit on the next line. overflow-wrap:
break-word wraps at word boundaries first and only breaks mid-word
when a single word exceeds the container width.
