Collapse the Great Wyrm War twin into history.events.the_great_wyrm_war

Follows package 142, which was canonized. Grounded on live canon_json reads of history.events.the_great_wyrm_war and military_conflicts.great_wyrm_war, including the seven canonized child conflicts (burning_of_vekh_zural, crossing_at_sosaaz, busyl_causeway, yuliz_sieges, netin_fojaa, urtkaa, siege_of_kaagaat) and the four incoming references on the event entity. All content sections carried verbatim from the military_conflict record; only the summary was edited, to remove a reviewer note canonized in error, and 'Zelguh Kairtis' corrected to 'Zelguu Kairtis' per history.characters.zelguu_kairtis.
