fix intermittent Bokeh widget render via output_notebook(resources=INLINE)

The diachronic-analysis plot uses RadioButtonGroup/Switch from
bokeh.models.widgets. With the default CDN autoload, Bokeh fires
embed_document as soon as window.Bokeh is defined (after bokeh.min.js
parses) — so on slow loads bokeh-widgets.min.js hasn't registered
RadioButtonGroup yet and the figure fails with "could not resolve type
'RadioButtonGroup'". Switching to INLINE resources embeds the full
BokehJS bundle synchronously in one script tag, eliminating the race.
