feat: 对称方式可选 - 垂直翻转 / 180° 旋转
为 JQK 人物图和大小王素材添加 symmetry_mode 字段: - 'flip'(默认):下半身用垂直镜像(沿水平中线翻转,左右不变) - 'rotate':下半身用 180° 旋转(上下颠倒 + 左右镜像) 改动: - 后端 draw_face_card / draw_joker:根据 symmetry_mode 选不同的 PIL transpose - 前端 cardRenderer.js:face card 和 joker 都用统一的分支: - flip: translate + scale(1, -1) - rotate: translate + rotate(Math.PI) - DesignPanel.vue:JQK/大小王面板加下拉选择器,存到 card_overrides
