dataset v2: code-review fixes

- Guard global class-list keydown against input focus (digits in search/dates no longer hijack the class filter)
- Relabel null-value status chip "None" → "All" to match its show-all behavior
- Filter savedAnnotations by selectedFlight when computing grandTotal
- Preserve seed indicator under selection (amber border + red ring)
- Reset to page 1 after bulk validate so the user isn't stranded
- Remove always-disabled Refresh Thumbnails button
- Lift class-distribution fetch into DatasetPage; pass counts down (one fetch, shared by sidebar and chart)
- Hoist Intl.DateTimeFormat to module scope; cache tile date per render
