feat(energy): 氢/电统一时间速选为「本周/本月/近15天」+ 缺失日补 0

- 后端 Range 类型精简到 thisWeek / thisMonth / last15
  rangeClause 同步精简；删除 today / thisQuarter / last7 / last30 分支
- 新增 enumerateDates(range)：列出 range 内全部日期，用于补零
- /hydrogen/daily：用 enumerateDates 补齐缺失日期 totalKg=0、stations=[]
  补零后基于完整日期序列重算环比（0→上一日有值时显示 -100%）
- /electric/monthly：增加 range 参数，扁平日聚合 + 月份分组
  缺失日期同样补零；环比基于补零序列重算
- 默认 range 改 last15

前端
- HydrogenDaily QUICK_PICK_OPTIONS 收紧到 3 项，默认 last15
- ElectricDaily 之前没有日期速选，现按氢能样式加上同样 3 项

类型 DateQuickPick 改 'thisWeek' | 'thisMonth' | 'last15'
