完善系统参数配置和数据字典管理模块

- 网关管理：GatewayEntity/Service/Controller CRUD + 测试连接；设备 GatewayId 外键关联
- JWT 认证：登录签发 Token（权限编码写入 Claims）、RequirePermission 权限过滤器、CurrentUser 上下文
- RBAC：用户/角色/权限实体与 CRUD，预定义 4 角色 + 6 权限种子（admin/admin123）
- 组织架构：sys_org 固定层级树（公司/实验室/部门/班组白夜班），层级校验，用户挂 OrgId/岗位/技能标签
- 数据权限：角色 DataScope（全部/本组织及下级），用户列表按组织子树过滤
- 防锁死保护：禁止删/禁自己，保证至少一名活跃管理员，角色摘除 user:manage 前校验
- 审计日志：AuditRecorder 接入设备增删改/指令下发/登录登出/组织变更，AuditController 查询
- 设备指令下发按网关表取连接参数；设备列表支持 gatewayId/productId 筛选
