v0.248.0: i18n slice 1 release A — apps and settings in English, Hungarian byte-identical (R-556)

Ten pages converted against fixtures captured from unconverted templates (6be55a0); marker
coverage test; English page mask narrowed; English retrieval-promise stems; common keys;
title keys and infraMeta from the bundle; old wording tests read the Hungarian expansion.
