feat(usage): Sub2API 中转站账单查询 + 模型发现列表全选/反选 — bump to v0.7.17

- 新增 balance:sub2api：GET {base}/v1/usage 复用推理 sk- key，解析 quota /
  5h·1d·7d rate_limits / 订阅组日周月额度 / 钱包余额（USD）
- detect_provider 修正 codingplan.site 家族：主域=Sub2API，ai.=NewAPI
- UsageConfigModal 新增 Sub2API 模板（无需凭据，可选 Base URL 覆盖）
- ProviderEdit 模型发现列表新增 全选/取消全选/反选
- cargo test 124 通过（+6 sub2api 解析用例）、tsc 零错误
