style(transfer): 树转让 3 页面从暗夜主题改为 App 标准浅色棕金主题

问题：树转让的 transfer_list_page、transfer_initiate_page、
transfer_detail_page 三个页面使用了深色暗夜主题（#1A1A2E 背景 +
#16213E 卡片），与 App 其余 40+ 功能页面的浅色棕金主题不一致。

修改内容（3 个文件，纯样式重写，零业务逻辑变更）：

1. 页面背景：#1A1A2E → 渐变 #FFF7E6 → #EAE0C8（与 planting_quantity_page 一致）
2. 卡片背景：#16213E → #99FFFFFF 半透明白 + boxShadow（与认种页一致）
3. AppBar：深色背景白字 → 透明背景 + 金色返回键(#D4AF37) + 棕色标题(#5D4037)
4. 正文文字：Colors.white/white70 → #5D4037 棕色 / #745D43 次级棕色
5. 输入框：#16213E 填充 → #99FFFFFF 填充 + #EAE0C8 边框
6. 按钮：ElevatedButton → GestureDetector+Container（高度 56，与全局一致）
7. 分割线：Colors.white24 → #EAE0C8
8. Tab 栏：暗色系 → 半透明白卡片容器 + 金色指示器
9. Saga 时间线未完成节点：white 20% → #EAE0C8 暖色
10. 对话框：系统默认 → #FFF7E6 背景 + 棕色文字

样式参考基准：planting_quantity_page.dart（现有认种数量页）
