Two changes combined:
1. historical-query-slow-connection: Migrate all historical query pages
to read_sql_df_slow with semaphore concurrency control (max 3),
raise DB slow timeout to 300s, gunicorn timeout to 360s, and
unify frontend timeouts to 360s for all historical pages.
2. hold-resource-history-dataset-cache: Convert hold-history and
resource-history from multi-query to single-query + dataset cache
pattern (L1 ProcessLevelCache + L2 Redis parquet/base64, TTL=900s).
Replace old GET endpoints with POST /query + GET /view two-phase
API. Frontend auto-retries on 410 cache_expired.

Reject History:
- Compute dimension pareto (package/type/workflow/workcenter/equipment) from
cached DataFrame instead of re-querying Oracle per dimension change
- Propagate supplementary filters and trend date selection to dimension pareto
- Add staleness tracking to prevent race conditions on rapid dimension switches
- Add WORKFLOWNAME to detail and export outputs
- Fix button hover visibility with CSS specificity
MSD (製程不良追溯分析):
- Separate raw events caching from aggregation computation so changing
loss_reasons uses EventFetcher per-domain cache (fast) and recomputes
aggregation with current filters instead of returning stale cached results
- Exclude loss_reasons from MSD seed cache key since seed resolution does
not use it, avoiding unnecessary Oracle re-queries
- Add suspect context panel, analysis summary, upstream station/spec filters
- Add machine bar click drill-down and filtered attribution charts
Query Tool:
- Support batch container_ids in lot CSV export (history/materials/rejects/holds)

Replace per-interaction Oracle queries with a two-phase model:
- POST /query: single Oracle hit, cache full LOT-level DataFrame (L1+L2)
- GET /view: read cache, apply supplementary/interactive filters via pandas
Add container query mode (LOT/工單/WAFER LOT with wildcard support),
supplementary filters (Package/WC GROUP/Reason) from cached data,
PB_* series exclusion (was PB_Diode only), and query loading spinner.

SQL CTEs now join on SPECNAME instead of WORKCENTERNAME to resolve
correct WORKCENTER/GROUP from DW_MES_SPEC_WORKCENTER_V, fixing cases
where the raw WORKCENTERNAME was mismatched (e.g. W/B-END with 成型_料).
WORKCENTER_GROUP filter converts groups→specs via cached mapping before
querying. Pareto chart now recalculates on legend toggle by spreading
the ECharts selected object to trigger Vue reactivity.

Add EQUIPMENTNAME and REJECTCOMMENT columns to the detail table, list SQL,
and per-LOT base query. Rewrite CSV export to use per-LOT rows with Chinese
headers, BOM UTF-8 encoding, and fetch-based blob download with loading
spinner. Sync trend chart legend filter (reject/defect) to detail table and
export via metric_filter parameter through the full stack. Fix chart sizing
with containLabel and autoresize throttle.
