fix: 预览标题坐标系与后端 ASS 烧录 1:1 对齐

问题：CSS 预览层硬编码 1280x720 坐标系，后端竖屏实际输出 1080x1920，
导致标题位置、字号、边距与最终渲染视频不一致，视觉上出现"标题重叠"。

修复（PreviewVideoPanel.tsx + FrontendPreviewPlayer.tsx）：
- 根据 videoRatio 动态选择后端实际分辨率：
  · 9:16 → 1080x1920
  · 16:9 → 1920x1080
  · 1:1 → 1080x1080
- 字号缩放分母从 720 改为实际 PlayResY，不设 96 上限
- 水平边距百分比分母从 1280 改为实际 PlayResX
- 垂直边距（top/bottom）按实际 PlayResY 计算百分比
- 描边宽度、阴影模糊/偏移按容器缩放比例同步放大
- FrontendPreviewPlayer 标题叠加层同时支持半角/和全角／换行
- 移除 paddingLeft/paddingRight hack，改用 left/right 边距（与 ASS MarginL/R 一致）
