On missing pages, add queries to highlight lexemes contained in the titles of relevant publications

to assist with the curation of related content, e.g. as demoed via
https://www.wikidata.org/wiki/Wikidata:University_of_Virginia/Listeria/UVa_people/Common_words_in_titles_of_UVA-coauthored_publications_without_P921_(main_subject)_statement .

I have tested and refined the SPARQL query for weeks and thought putting it into Scholia would be a quick act, but no, could not get it to work there.

Progress so far is in https://github.com/fnielsen/scholia/tree/feat/ngrams-for-topics-1129 , which also has a debug section in topic_missing.html that I am using to try to identify what the problem is.

Some intermediate results from the debugging, as per screenshots for
topic/Q1659584/missing (ImageJ)
and
/topic/Q84263196/missing (COVID-19).

Note that the focus of the debugging queries is on seeing whether the results render, with some of the missing bits hardcoded, which explains why ImageJ is showing up under COVID-19.
