feat(records): 训练勋章 UI 改造

- 勋章图标从 emoji 改为矢量 SVG 线性图标（utils/icons.js 新增 bolt/moon/diamond 路径及 white 变体）
- 命名改为累计语义（一周累计/半月累计/月度累计/双月累计/百日累计），并标注"非连续打卡"
- 进度条改回等距节点，解锁时填充正好抵达节点、满级满格
- 新增单枚解锁庆祝：持久化已见解锁集合，进入页面弹 toast + 节点 pop 动画
- 已解锁节点常驻显示勋章名 + 右上角 ✓ 角标，直观体现"已拥有"
- utils/storage.js 新增 totalDays（累计去重训练日），为勋章统计提供数据源
