fix(reject-history): WORKORDER bind variable error + move policy filters to in-memory

Three fixes for the reject history query feature:

1. Fix DPY-4010 bind variable error when querying by WORKORDER — the
   workflow_lookup CTE had hardcoded :start_date/:end_date which aren't
   provided in container mode. Replaced with {{ WORKFLOW_FILTER }} template
   slot that defaults to date-based filter or container-based filter.

2. Move policy toggle filters (material scrap, PB_diode, excluded reasons)
   from SQL-level to in-memory pandas filtering. Cache now stores unfiltered
   data so toggling policy filters reuses cached results instantly instead
   of requiring a ~30s Oracle round-trip per combination.

3. Add per-WORKORDER expansion_info display in FilterPanel for multi-order
   container resolution diagnostics.
