refactor: 平台改为代码内置 provider 架构，一次性迁移现有数据 - 新增 app/providers：BalanceProvider 基类 + DeepSeek 适配器 + 注册表 - platforms 表去除 method/url/headers/body/balance_path，新增 provider_id - 现有数据库已一次性迁移（备份 data/monitor.db.bak-v1），不保留迁移工具 - 平台 UI 改为选择内置提供方；fetcher/monitor 走 provider 构建请求与解析 - 表达式引擎（运算符/函数）随架构保留，供 provider 内部使用 - 测试更新至 provider 模式，共 92 个
