fix(query-tool): export all selected CIDs instead of single, fix hold detail float precision

Export was sending only one container_id while the detail table loaded
data for all selected CIDs (including subtree), causing "查無資料" errors.
Now sends container_ids array and uses batch service functions.

Also rounds hold detail age KPI cards to 1 decimal place.
