feat: 简化字段卡片交互 - 点击直接打开编辑弹窗

- 移除字段卡片选中样式
- 点击字段直接打开编辑弹窗
- 简化 FieldItem 组件，移除 isSelected 属性
- 简化 FieldList 接口，onSelect 改为 onEdit

fix: 优化字段编辑弹窗

- 去除弹窗描述文字
- 字段名称增加字符计数 (x/20)
- 字段描述增加字符计数 (x/50)
- 保持 placeholder 提示

fix: 修复弹窗顶部间距问题

- DialogContent 添加 pt-6 避开关闭按钮
- 内容区域移除顶部 padding，改为 pb-6

fix: 增加弹窗顶部间距 (pt-6 → pt-8)

fix: 优化弹窗尺寸和按钮间距

- 弹窗最大宽度 360→420px 适配标签页
- 增加按钮 padding (px-2→px-3, py-1→py-1.5)
- 添加按钮增加 padding (h-8→h-9, px-3)
