fix(scripts): drop the retired research-mode columns from the demo rebuild

The demo edge01 rebuild copies the users table by an explicit column list,
and three of the names in it — research_mode_enabled and its two
acknowledgment stamps — were dropped from the schema when Research Mode was
retired. The COPY and its matching SELECT both targeted columns that no
longer exist, so the rebuild would fail on the first users row. Removed from
both lists, which stay aligned.
