fix(style): prevent page overflow

Pages with wide horizontal content could horizontally scroll on mobile due to `.page-wrapper` not having fixed width in f851142fb2

Re-add overflow-wrap which was removed in e6dba41f3d (in attempt to simplify logic).

Add horizontal scroll to unresponsive Plotly charts.

Also, refactor chart style and refactor callout styles into dedicated file.
