feat: 新增部分套餐账单查询（v0.6.4）

- 账单/用量查询：balance:kimi（Moonshot 开放平台余额）、NewAPI 中转站余额（accessToken+userId）、Kimi/智谱/MiniMax 套餐档位（5小时/7天）
- managed:kimi-code 走 Kimi Code OAuth 登录凭据查询订阅用量，access token 过期自动 refresh 并写回凭据（单 flight 锁 + 写回前重读防 CLI 竞态）
- 全屏「配置用量查询」页面：启用开关 / 自动检测 vs NewAPI 模板 / 超时与自动查询间隔 / 测试查询
- 供应商卡片紧凑用量行（切换使用左侧）+ 多档明细行；managed 供应商列表置顶（仅展示层）
- 用量显示中英文适配（five_hour→5小时、weekly_limit→7天，Rust 错误串本地化映射）
- 修复：usage_kinds serde rename 导致账单入口不显示；测试查询因 save 触发 loading 翻页卸载面板导致结果丢失（silent save）
