Replace hardcoded user-visible strings in 12 scene scripts (great_person_modal,
merge_panel, specialists_drag_panel, throne_room_great_works,
intelligence_log_panel, knowledge_tree tier badge, credits, game_setup,
past_games, replay_viewer, lens_switcher/ransom_offers tooltips) with
ThemeVocabulary.lookup() + add the corresponding keys (incl. fmt_* for format
strings). Part of clearing validate-i18n with no bypass. (48 → 23 remaining.)
