fix: refine Magic Notes editing layout

The Magic Notes editor had ambiguous font-size labels, cramped pane spacing, and a fixed short writing area. The toolbar now groups controls and uses numeric sizes, the pane and empty states are balanced, and the editor can be resized vertically from a taller default.

Release note: 优化魔法笔记编辑体验：字号改为数字、工具栏与分栏布局更清晰，输入区域支持纵向拖拽并默认显示更多内容。
