fix(activity-log): post-test polish - localize descriptions, dashboard widget, ticking time

- localize entry descriptions client-side via localizeMessage (activity_log.msg.* + entity_type.* templates x3 locales); server message kept as fallback/export/search
- remove redundant Activity header banner from tab
- Recent Activity widget is now a first-class dashboard section (Customize Dashboard show/hide/reorder; pre-existing layouts preserved)
- live activity event updates the widget surgically (no full dashboard rebuild); single listener with teardown
- relative-time labels tick via shared ensureRelativeTimeTicker (single 30s interval, visibility-aware)
