feat(rectification): confirm the tap on the choice card and show the declared minute on the empty board

The selected option carries a check and 已选择, and a card whose tap is
being recorded shows one inline-spinner row 正在记录… (the timeline row's
shape, not a new vocabulary). Before any candidate exists the board's clock
shows the profile's declared birth minute with two lines of copy, the peek
reads 当前盘面 · 填报 HH:MM, and the column narrows until a result arrives.
The snapshot API has no declared-time house table, so none is invented.
