fix(hold): dedup equipment cache, fix portal iframe, improve Hold dashboards

- Equipment cache: add freshness gate so only 1 Oracle query per 5-min cycle
  across 4 gunicorn workers; sync worker waits before first refresh
- Portal: add frame-busting to prevent recursive iframe nesting
- Hold Overview: remove redundant TreeMap, add Product & Future Hold Comment
  columns to LotTable
- Hold History: switch list.sql JOIN from DW_MES_LOT_V (WIP snapshot) to
  DW_MES_CONTAINER (historical master) for reliable Product data; add
  Future Hold Comment column; fix comment truncation with hover tooltip
- Page status: reorganize drawer groupings
