style(mini-program): 优化生成剧本按钮样式与原型一致

修改内容:
- ScriptView.vue.generate-btn: 添加渐变背景、文字居中、调整圆角为 32rpx
- App.vue.btn-primary: 添加文字居中样式 (display: flex + align/justify)

样式变更:
- 背景：添加 linear-gradient(135deg, #9333EA 0%, #7C3AED 100%)
- 文字：垂直和水平居中对齐
- 圆角：40rpx → 32rpx（与原型 rounded-2xl 一致）
- 保持：高度 96rpx、阴影效果

解决 issues: 小程序"创造未来"页面生成按钮文字不居中，
            与原型图视觉效果不一致
