feat(mid-section-defect): add TMTT reverse traceability analysis with paginated detail API

New page for tracing TMTT test station defects back to upstream machines,
stations, and workflows. Three-stage data pipeline (TMTT detection →
SPLITFROMID BFS + COMBINEDASSYLOTS merge expansion → upstream history),
6 KPI cards, 6 Pareto charts, daily trend, paginated LOT detail table.

Summary/detail API separation reduces response from 72 MB to ~16 KB summary
+ ~110 KB/page detail. Loss reasons cached in Redis with 24h TTL (205 types).
