LOT Page Refactoring (2026-02-10)

What was done:

Created new dedicated /lot page with two tabs:
1. LOT tab: Component/article management (table with search, sort, create LOT)
2. Сопоставления tab: partnumber ↔ LOT mappings management
Removed LOT tab from "Администратор цен" (Pricing Admin)
Removed "Сопоставление partnumber → LOT" section from Warehouse tab
Updated main menu navigation:
- LOT link → /lot (new page)
- Администратор цен → /admin/pricing (Estimate, Склад, Конкуренты)
- Настройки (unchanged)

Files changed:

web/templates/lot.html (NEW) - Complete page with LOT and stock mappings tabs
web/templates/base.html - Updated menu to link LOT to /lot
web/templates/admin_pricing.html - Removed LOT tab, changed default to Estimate
internal/handlers/web.go - Added lot.html to template list, added Lot() handler
cmd/pfs/main.go - Added /lot route

Technical notes:

lot.html uses same API endpoints as admin_pricing for data loading
Stock mappings functions copied from admin_pricing.html but adapted for new page
Default tab for Pricing Admin is now 'estimate' instead of 'lots'

Never derive category from item name (lot name). Always use category from PricelistItem (lot_category / JSON category).
