Use Daily Trend as single source of truth for On Hold and New Hold KPI cards
instead of separate snapshot SQL queries, eliminating value mismatches. Fix
timezone bug in default date range (toISOString UTC offset), add 1st-of-month
fallback to previous month, replace Hold Type radio buttons with select dropdown,
reorder/relabel summary cards with 累計 prefix, add job-query MultiSelect for
equipment filter, and fix heatmap chart X-axis overlap with visualMap legend.
