Add PACKAGE_LEF as a dedicated `package` field in the QC-GATE API payload
and display it as a new column after LOT ID in LotTable.vue. Archive
qc-gate-lot-package-column, historical-query-slow-connection, and
msd-multifactor-backward-tracing changes with their delta specs synced
to main specs.

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.

New independent report page based on DWH.DW_MES_HOLDRELEASEHISTORY providing
historical hold/release performance analysis. Includes daily trend with Redis
caching, reason Pareto with click-to-filter, duration distribution with
click-to-filter, multi-select record type filter (new/on_hold/released),
workcenter-group mapping via memory cache, and server-side paginated detail
table. All 32 backend tests passing.
