feat(wiki): surface D-237 specialization fields in the system infobox

generate_infobox() now renders economic_specialization (Specialization) and
cultural_specialization (Cultural Register) as read-only infobox rows when
authored (NULL = omitted, falls to heuristic). dominant_faction already
showed via Governance. Makes the authored generator-input values visible on
the wiki face so the #1016 content pass output renders. Verified: Ran shows
'breadbasket'/'agrarian'; unauthored systems omit the rows.
