feat(mcp): apply Unpack decorator to all remaining MCP tools

Apply the @unpack_pydantic_params decorator to all remaining MCP tools to
enable flat parameter calls from Claude Code.

Tools updated:
- catalog.py: create_product, create_material
- items.py: search_items
- purchase_orders.py: create_purchase_order, receive_purchase_order, verify_order_document
- manufacturing_orders.py: create_manufacturing_order
- orders.py: fulfill_order

All 10 MCP tools now support flat parameters like:
  mcp__katana-erp__search_items(query="widget", limit=10)

Instead of requiring nested request objects like:
  mcp__katana-erp__search_items(request={"query": "widget", "limit": 10})

This completes the rollout of the Unpack decorator to the entire MCP server.
