feat(task-buttons): 外链按钮新增「打开方式」（新窗口/当前窗口）

按钮管理（/page/strategy/admin/task-buttons）的 url 外链按钮可配置打开方式：
- blank=新窗口（默认，window.open(_blank)，行为同改前）
- self=当前窗口（window.location.assign，嵌入态即当前 iframe）

新增 TaskButton.openMode 字段贯通前后端：前端 task-buttons.ts 类型+种子+
runTaskButton 打开逻辑、api 客户端 snake⇄camel 映射、TaskButtonsPage 下拉；
后端 router schema + ORM open_mode 列（可空默认 blank，启动自动 ALTER 补列，
无需手动迁移）+ sql/memory store 归一化。仅 url 类型生效。
