feat(rbac): RbacStore 持久化权限体系替代硬编码 UserStore
- 新增 PageCatalog / RbacModels / RbacStore / RbacController：用户、角色、页面/操作/控件授权落盘 data/rbac.json，支持运行时增删改并即时生效 - 密码改用 PBKDF2-SHA256(100k 迭代 + 16B 随机盐) 存储，校验走 FixedTimeEquals 防时序攻击；对外 DTO 绝不外泄盐/哈希 - AuthController 登录 / me / switch-scope 统一收敛到 BuildSession，按角色在当前 scope 的并集计算有效权限并签发 JWT - EffectivePermissions 增加 AllowedPages；移除旧的硬编码 UserStore - Program.cs 注册 RbacStore、新增 RbacAdmin 授权策略（ops claim 含 * 或 auth.manage），并按 SimpleLite:FollowParent 决定是否注册停机清理钩子
