+PMS 登录与权限 —— 认证解析 / 角色判定 / 会话票签验 / 接口鉴权判定（纯函数）
+=======================================================================
+方案见「PMS 加登录与两个角色（交易系统管理员 / 交易员）」。本模块刻意只放纯函数：
+不连库、几乎不联网，喂进去字典或字符串就能算，便于单测
+（scripts/test_batch18_units.py）。唯一碰网络的是 call_bshop_login 一个函数，
+它把真正的 HTTP 调用隔离出来，其余全部可离线测。
+
+三块职责：
+  一、认证：解析第三方登录系统 bshop 的登录返回（parse_bshop_login）。
+  二、角色：从 bshop 返回的权限清单里认出交易系统管理员 / 交易员（role_from_permissions）。
+  三、会话与鉴权：自签会话票（make_session / verify_session），以及按「方法 + 路径」
+      判这个请求要什么角色（authz_decision）。
+
+会话票格式：base64url( json({phone, username, role, exp}) ) + "." + base64url( hmac_sha256 )
+  —— 只用标准库 hmac / hashlib，不引新依赖。exp 是 Unix 秒。

+  2. 会话票 make_session / verify_session: 签发-校验往返, 篡改/过期/换密钥/空密钥一律拒;

+  4. 接口鉴权 authz_decision + is_public_path: 「写操作默认拒绝」——交易员白名单外的写接口
+     一律要管理员 (专门钉死 /api/macro/adopt、POST /api/proposals、.../archive 与 .../cancel
