feat(queue): improve mobile responsiveness for QueuePage

- Summary cards: 2-col mobile grid with responsive padding, icons, and text sizing; 5th card spans full width on 2-col layout
- Filters: flex-wrap with scaled text/padding; selects share width on mobile; clear history button goes full-width
- Section headers (Pending/History): flex-wrap so sort controls wrap below title; drag hint hidden on mobile; responsive icon and text sizes
- Bulk action toolbar: flex-wrap with tighter gaps/padding; vertical divider hidden on mobile; scaled button text and icons
- SortableQueueItem: top-aligned on mobile; smaller thumbnail (10→14 at sm); metadata row wraps with truncated printer name; username hidden on mobile; badges scale down; status badge and actions stack vertically on mobile; tighter button padding
