feat(auth+config+workflow+message+plugin): 为 5 个基础模块添加 permissions() 声明

- erp-auth: 23 个权限码（用户/角色/权限/组织/部门/岗位）
- erp-config: 18 个权限码（字典/菜单/配置/编号/主题/语言）
- erp-workflow: 8 个权限码（流程定义/实例/任务）
- erp-message: 5 个权限码（消息/模板），补充缺失的 message.template.manage
- erp-plugin: 2 个权限码（插件管理/查看）
- 同步更新 seed.rs 的 READ_PERM_INDICES 索引和权限计数

使得 sync_module_permissions() 可以动态注册这些权限，与 erp-health/erp-dialysis/erp-ai 模式一致。
