♻️ refactor(line-items): deprecate LineItemsContainer, add LineItems standalone component

[acasazza]

Summary

Refactors the line items components following the same pattern used by orders, prices, and SKU lists.

Changes

@commercelayer/core

• line_items/getLineItems.ts — fetches an order's line items with full includes (line_item_options.sku_option, item)
• line_items/updateLineItem.ts — updates quantity / external price flag
• line_items/deleteLineItem.ts — deletes a line item

@commercelayer/hooks

• useLineItems({ accessToken, orderId, interceptors? }) — SWR-based hook exposing lineItems, isLoading, error, updateLineItem, deleteLineItem, reload, mutate

@commercelayer/react-components

• New LineItems standalone component — no OrderContext required
  • Props: accessToken, orderId, types? (filter by item_type), loader?, onUpdate?, onDelete?
  • Uses useLineItems internally; feeds LineItemContext privately so all child components work unchanged
• LineItemsContainer marked @deprecated → migrate to <LineItems>
• LineItemContext — added reload?() to context value type
• LineItemsCount — fixed contextComponentName warning (LineItemsContainer → LineItems)

Improvements over old container

	LineItemsContainer	LineItems
Requires OrderContext	✅	❌
types filter	❌ (defined, never used)	✅
onUpdate / onDelete callbacks	❌	✅
reload() in context	❌	✅

Usage

<LineItems
  accessToken={token}
  orderId={id}
  types={["skus", "bundles"]}
  onDelete={(id) => toast(`Item ${id} removed`)}
>
  <LineItem>
    <LineItemName />
    <LineItemQuantity />
    <LineItemRemoveLink />
  </LineItem>
  <LineItemsCount />
  <LineItemsEmpty />
</LineItems>
