Event-only modal cache + Settings edit gating + ES i18n polish

Modal caches now refresh on events only — the periodic prewarmer runs one-shot at startup, mount points split into static/runtime endpoints, and backups get a client 6-hour gate. Updates tab shows post-apply feedback and the script terminal no longer closes the parent modal. Settings adds edit gating on 3 cards with the 3-level contrast rule applied consistently. ES translation batch (~25 fixes) and What's New for 1.2.4.1-beta refreshed.
