-约定（web-application-spec）：
-  - 一个应用 = 一个入口 = 一个端口（本项目 9300，与 conf/config.json、
-    projects/pbls/env/{test,prod}.json 三方同值）
-  - init() 内 ServerEnv() 先于 load_rbac()，再逐个显式 load_XXX()
-  - 模块取库名一律走 ServerEnv().get_module_dbname('模块名')，禁止硬编码 DBNAME
-  - 挂载顺序以 projects/pbls/pbls_spec.json 的 load_order 为准（23 个模块）
-  - HTTP 服务只由 ahserver 提供，不引入任何第三方 Web 框架或自建路由/序列化装饰器
