feat: 前后端联调 — 任务创建 + 账户信息 + 预估花费 (0.0.18)

- task: device_id 改为必填参数，API 层 Omit 封装 + getDeviceId() 自动注入
- pricing.ts: Python 后端 calculate_cost 完整移植，六种定价模式 + 6 个 Bug 修复
  (浮点冗余/维度匹配不一致/null 守卫/matrix 数据提取/unit_scale 等)
- ModelInputForm: 三层兜底预估消费展示 + React Hooks 顺序修复
- AccountInfo: VIP 等级列表匹配，套餐详情展示（说明/周期/席位/到期）
- 模型列表加密缓存 (safe-storage, stale-while-revalidate)
- VIP API 模块 (激活码/等级/订单/模拟支付)
- device_id 统一使用 UUID v4 持久化 (与 login/register 对齐)
