fix(energy): 顶部双 sticky 间隙泄露 + 加氢站名单价完整显示

问题 1：原本「氢能/电能/ETC」与「每日/总览」是两个独立的 sticky
元素，分别 top:0 / top:[58px]，中间 gap-3 +位置不精确导致滚动时
图表内容从 14px 缝隙里穿过。

修复：
- 把 HydrogenView 内部的 sub-tab 状态提到 EnergyModule
- top tab + 子 tab 合并到「同一张白色 rounded-2xl 卡片」里，无内部间隙
- 外层 sticky 容器 frosted glass：bg-[#F8F9FB]/85 + backdrop-blur-md
  -mx -mt 扩到页面边，消除左右上的微缝
- HydrogenView 改为受控组件（接收 sub prop）

问题 2：站点行 mobile 上 name + ' · 价格' 共用一格还 truncate，
导致长名称（广州新锋交通联新…/上海浦江加氢站…）截断、单价不可见。

修复：
- 行改为「站名换行 + 下方单价 chip」纵向排列
- 单价用 amber 小徽章「单价 X 元/Kg」，不再 inline 跟着名字
- name 用 break-words 允许折行，items-start 顶部对齐
- 单价为 0（免费/赠送）时不显示徽章，desktop 列里显示「—」
