phase1c: web UI — sidebar layout + list/form pages for catalog
Shared components:
- AppLayout with grouped sidebar nav (Главное / Каталог / Контрагенты / Склады / Справочники)
- DataTable, Pagination, SearchBar, Button, Modal, Field (TextInput/TextArea/Select/Checkbox)
- PageHeader, useCatalogList + useCatalogMutations hooks (TanStack Query)
- types.ts with enums as const objects (erasableSyntaxOnly-compatible)
Dashboard: 4 stat cards (products/counterparties/stores/retail-points counts) + roadmap
List + edit-in-modal for 9 entities:
- Countries, Currencies (read-only)
- VatRates, UnitsOfMeasure, PriceTypes, Stores, RetailPoints, ProductGroups, Counterparties (full CRUD)
- Products: list + filters; full form deferred to next commit
All pages: search, pagination, row-click → modal edit, create button, delete with confirm.
Counterparty form uses Country lookup; RetailPoint form uses Store lookup.
