URL is now single source of truth for filter state (workorder, lotid,
package, type, status) across WIP Overview and Detail pages. Drill-down
carries all filters + status; back button dynamically reflects Detail
changes. Backend Detail API now supports pj_type filter parameter.
Harden concurrency: add pagehide abort for MPA navigation, double-check
locking on Redis JSON parse and snapshot build to prevent thread pool
saturation during rapid page switching. Fix watchdog setsid and PID
discovery. Fix test_realtime_equipment_cache RUNCARDLOTID field mismatch.

Migrate /wip-overview, /wip-detail, and /hold-detail (1,941 lines vanilla JS)
to Vue 3 SFC architecture. Extract shared CSS/constants/components to
wip-shared/. Switch Pareto charts to vue-echarts with autoresize. Replace
Jinja2 template injection with frontend URL params + constant classification
for Hold Detail. Add 10-min auto-refresh + AbortController to Hold Detail.
Remove three Jinja2 templates, update Flask routes to send_from_directory.
