Title: (PDB-809) Store top level structured fact data as JSON

This adds the storage of the top level facts that happen to be structured in a
new column of fact_values called `value_json`. This is provided so we can query
top level facts for the /facts endpoint in a performant way, without having
to also reassemble the pieces of values into a JSON object later on.
