fix(studio-ds): P5 评审收口——a11y + 文案 + 注释清理

- 补 icon-only 按钮 aria-label:Feed 上/下切换(common.action.prev/next)
- GameCard 封面播放区键盘可达:role=button/tabindex/aria-label/@keydown.enter.space
- 新增 common.action.prev/next 中英文案;删 InteractBar 过期注释(flag 已补)

P5 of HJ-FE-DS-001。opus 评审无 P0、逻辑保真经机器 diff 实证;修 P1-1 无障碍。
