v1.4.0

What's new

• Copy-on-drag: hold Ctrl/Cmd while dragging (desktop) or tap the hint chip during drag (touch) to duplicate the selection instead of moving it — also works across pages.
• Page reordering: drag page tabs left/right to reorder pages; the bar live-reorders during the drag.
• Page tabs highlight during an item drag to signal cross-page drops are possible.
• Entity button active-state colors: separate active_background_color and active_icon_color applied automatically when the entity is active.
• Fully configurable Number Pad keys: per-key icon, text, colors, tap/hold action, plus a show/hide toggle (layout keeps the slot stable).
• Per-item X delete button removed — prevented accidental deletions on touch. Items are now deleted by dragging them onto the trash zone.
• Minor bug fixes and editor layout polish.
