"""插件管理路由（PLG-QUERY-01/02 + PLG-LIFE-01~07 + PLG-INSTALL + PLG-UNINSTALL-FILE + PLG-CONFIG + PLG-BATCH-LIFE）。

统一采用模板 A（控制面端口路由），鉴权依赖 get_admin_user，调用
use_cases.plugin_management.<method>，raiseOnControlFailure 转译失败，
serialize_control_data 序列化响应。

路径设计：静态路径 /plugins 先于动态路径 /plugins/{plugin_id} 及其子路径
声明（规范 §6.5），避免静态路径被动态参数捕获（如 plugin_id="schema"
被 /plugins 捕获）。子 router 自身 prefix 为 /plugins，根前缀 /channels
由 channels_router 聚合 router 统一追加。

端点清单（对应《09-插件管理域设计方案》§2.1）：
    - GET   /plugins                       PLG-QUERY-01 listPlugins

    - POST  /plugins/{plugin_id}/load      PLG-LIFE-01  pluginLoad
    - POST  /plugins/{plugin_id}/start     PLG-LIFE-02  pluginStart
    - POST  /plugins/{plugin_id}/pause     PLG-LIFE-03  pluginPause
    - POST  /plugins/{plugin_id}/resume    PLG-LIFE-04  pluginResume
