fix(dsh): 套餐级概览按档位自己的标签取，Teams/Provider 不再一行都没有

目标要求「Teams 只给套餐级」，但视图里的概览行是按套餐名做前缀匹配找的：
Teams 与 Provider 没有 per-model 页、也就没有 planName，于是连套餐级数字都拿不到；
Max 与 Ultra 还会都被前缀匹配到 Max 10× 那一行。

- 概览行改按档位自己的标签查（PLAN_LEVEL_LABELS），并把它同时当作无名档位的显示名。
- 修后：Ultra → Max 20×（~370K）并继续标注「按 Max 推断」；Max → Max 10×（~230K）；
  Provider → Provider API API access 那一行；Teams → Team Pro（~35K requests）。
- 测试同步为「没有 per-model 页的档位仍有名字与套餐级概览」，离线校验 244 项保持全绿。
