v0.13.0 — Inventory (HomeBox): durable items that nest

The first inventory vertical on the shared spine. Things you own — tools, gear,
equipment — each living in a Location or inside another Item.

- Item model (kind DURABLE|CONSUMABLE; consumable fields present but unused so
  Pantry needs no migration), self-nesting via parentItemId (toolbox holds drill,
  with a cycle guard), value/warranty/serial/brand/qty, qrSlug, photo
- Label (m2m) + ItemAttachment (photos/manuals/receipts) + ItemLog
  (maintenance/repair/move/dispose) history; Task.itemId
- API-first: /api/v1/items (CRUD), labels, logs, multipart attachments — the UI
  consumes the same scoped endpoints. items service shared with the coming MCP
- Inventory pages: tree grouped by Location with items nested inside items;
  item detail with warranty status, photos, contents, history; add/edit/delete,
  log, photo upload. Nav entry. Backup/restore cover the new tables
- Pure value.ts (warrantyStatus, totalValue) with tests; verified end-to-end
  against a running server (nest, cycle-guard 400, log 201)
