Replace competitor discount with price_uplift; stock pricelist detail UI
- Drop `expected_discount_pct`, add `price_uplift DECIMAL(8,4) DEFAULT 1.3`
to `qt_competitors` (migration 040); formula: effective_price = price / uplift
- Extend `LoadLotMetrics` to return per-PN qty map (`pnQtysByLot`)
- Add virtual fields `CompetitorNames`, `PriceSpreadPct`, `PartnumberQtys`
to `PricelistItem`; populate via `enrichWarehouseItems` / `enrichCompetitorItems`
- Competitor quotes filtered to qty > 0 before lot resolution
- New "stock layout" on pricelist detail page for warehouse/competitor:
Partnumbers column (PN + qty, only qty>0), Поставщик column, no Настройки/Доступно
- Spread badge ±N% shown next to price for competitor rows
- Bible updated: pricelist.md, history.md
