fix(assets): 区域车型分解新增「待交车」字段，并合入「其他」车型

- typeBreakdown 之前只产 4.5T/18T/49T 且仅含 inventory 字段，
  导致区域级 待交车 与车型级 待:N 不一致、操作中合计 != 区域合计
- 后端 getTypeBreakdown 计算 pending（status==='Pending'），
  并把不属 4.5T/18T/49T 的车辆聚合为「其他」类型
- 前端区域 mobile/desktop 视图把「待:」从 inventory 改读 pending
- 点击穿透的 category 也由 'Inventory' 改 'Pending'
