feat(ui): redesign updates center into action inbox

- replace release-note-heavy layout with task-first action inbox

- add persistent local notice progress states (new/seen/done/dismissed)

- introduce actionable notice metadata and related integration mapping

- keep full-page shell fixed with internal scrolling only
