Refactor: 群记忆重构为房间规则并新增私密群组付费功能

- **群记忆重构:**
    - 将群记忆（Group Memory）的底层实现从 `AgentRule`（智能体规则）重构为 `RoomRule`（房间规则）。
    - ViewModel 中相关的数据和服务调用已全部更新，以使用 `RoomService` 和 `RoomRuleEntity`。
    - 移除了获取智能体 `openId` 的相关逻辑。

- **私密群组付费:**
    - 新增设置群组为私密时的派币付费流程。
    - 用户设置私密群组时，若未支付过费用，将弹出付费确认对话框，显示所需费用和账户余额。
    - `GroupInfo` 实体新增 `trtcType` 和 `privateFeePaid` 字段，用于判断群组可见性状态和付费状态。
    - UI 逻辑更新，根据付费状态显示不同的提示信息（如 "待解锁"、派币费用）。

- **UI 优化:**
    - 移除群信息页中已废弃的 "解锁群扩展" 横幅。
    - 记忆管理弹窗现在会立即展开到全屏，优化了显示动画。
    - 动态显示添加群记忆所需的派币消耗。
