Inbox: replace 4 parallel outlined buttons with 2 context-aware ones. When nothing is selected → "Acknowledge all firing" (primary) + "Mark all read" (secondary). When rows are selected → the same slots become "Acknowledge N" + "Mark N read" with counts inlined. Primary variant gives the foreground action proper visual weight; secondary is the supporting action. No more visually-identical disabled buttons cluttering the bar. History: drop the local DateRangePicker. The page now reads `timeRange` from `useGlobalFilters()` so the top-bar TimeRangeDropdown (1h / 3h / 6h / Today / 24h / 7d / custom) is the single source of truth, consistent with every other time-scoped page in the app.
