feat(backend): license_devices 表 + 注册自动签发 trial (21B+21C)

21B — DB & model:
- licenses: 扩展 license_key 为 2048 字节（容纳 Ed25519 JWT），
  新增 max_devices INT DEFAULT 3，device_id/activated_at 标为 deprecated
- 新增 license_devices 表（license_id+device_id 唯一索引）
- model/license_device.go：LicenseDevice struct
- main.go AutoMigrate 加入 LicenseDevice
- testutil/setup.go 同步 SQLite DDL

21C — trial at register:
- config: 新增 Ed25519PrivateKey 配置项（LICENSE_ED25519_PRIVATE_KEY 环境变量）
- service/license.go: createTrialLicense(tx, shopID) — 签发 30d trial，
  私钥未配置时静默跳过（开发/测试不影响）
- service/auth.go: Register 事务末尾调用 createTrialLicense
