feat: 实现 16:9 9:16 视频宽高比转换功能

主要改进:
- 修复前端模板选择与后端识别不匹配问题
- 解决驼峰命名法与下划线命名法转换问题
- 实现正确的宽高比转换滤镜链 (tvai_up + scale + crop)
- 添加模板名称传递机制避免硬编码推断
- 优化 NVENC 编码器分辨率限制处理
- 支持 16:99:16 和 9:1616:9 双向转换

技术细节:
- 前端: 修复 outSizeMethod 字段为 undefined 的问题
- 后端: 添加 template_name 字段到 WebTopazSettings
- 滤镜: 使用独立的 scale 和 crop 滤镜实现精确转换
- 调试: 增加详细的调试信息便于问题排查
