v0.23.0 — Pantry: structured USED pull logs + move to /api/v1 service layer

Pantry now runs on the v1 API like Inventory/Animals: service layer in
src/lib/services/pantry.ts, pure logic + tests in src/lib/pantry/core.ts,
thin routes at /api/v1/pantry/* riding the items:* scopes. Pulls write
ItemLog type USED with a structured amount (queryable consumption).
Bulk-use runs its reads inside the transaction, accumulates repeated
pulls, and reports skipped items instead of silently dropping them —
the Pull dialog now surfaces those by name. Old /api/pantry routes
deleted.
