bug: inventory add endpoint requires 'name' and 'item_type' but frontend sends 'item_name' — always 422

[Sealjay]

Summary

POST /inventory/{character_id}/add returns 422 because the frontend sends item_name but the backend Pydantic model requires name and additionally requires item_type:

{"detail": [
  {"type": "missing", "loc": ["body", "name"], "msg": "Field required"},
  {"type": "missing", "loc": ["body", "item_type"], "msg": "Field required"}
]}

The frontend InventoryItem interface uses name (correct), but wherever items are constructed from predefined character data they use item_id as the primary identifier (see #620). Additionally the item_type field has no default value and is required, but is not present in the frontend InventoryItem interface.

This means the entire inventory management system is broken — no items can be added.

• frontend/src/services/api.ts — InventoryItem interface missing item_type

Fix

Either add item_type with a sensible default (e.g., 'misc') to the Pydantic model, or make it optional.
