Anonymous callers get a free cumulative quota (1000 calls per IP); once
exhausted they get 403 quota_exhausted and must register. Public users can
self-register (email+password) to obtain a higher-quota API key, view usage,
and regenerate the key. Quota counters live in Redis; the public API stays
read-only except for the registration writes.
- migration 0011: app_user table + api_key.quota_total + 'registered' tier
- ratelimit: IncrTotal/TotalUsed/CopyTotal lifetime counters
- middleware: enforce cumulative quota + X-Quota-* headers
- store: RegisterUser/Authenticate/RegenerateKey (bcrypt)
- handlers: POST /api/v1/register, /account, /account/regenerate
- admin: quota_total column + registered tier
- public: 'API 密钥' account page + API docs quota section

品牌管理：列出品牌及引用商品数，支持改名、合并重复品牌（把源品牌的商品并入目标后删除源）、删除未被引用的品牌。新建商品：商品列表新增「新建商品」入口，填写名称/条码/品牌/品类后创建并进入详情页继续补全。

Wire the multi-barcode store layer to HTTP and the operator console:
- adminhandler: add POST /products/{id}/barcodes, DELETE
/products/{id}/barcodes/{barcodeID}, and POST .../primary. A barcode
owned by another product returns 409 with the conflicting product
(gtin/product_id/product_name); an invalid GTIN returns 400.
- admin-frontend: BarcodesCard on the product detail page lists all
barcodes (primary starred), adds with type/pack-level/region, sets
primary, and deletes; audit labels for the new actions.
- public-frontend: product detail surfaces non-primary barcodes so a
case/region code resolves and is visible to consumers.
