C2CSetting State

Introduction
C2CSettingState is a status management center related to personal setting, specialized in managing the status and operations of 1v1 (C2C) chat settings. It provides user information management, chat settings control, friend relationship queries, and other features, serving as a core tool for building one-on-one chat settings interface.
C2CSettingState can automatically listen to changes in the current session. When entering a C2C session, it automatically retrieves the other party's user information and chat settings, and provides convenient operations to modify pinned, do not disturb, remark, and other settings.

Key Usage Points
This example shows how to:
1. User information display - Use fields such as userID, nick, avatar, and signature to show complete user information.
2. Friend relationship flag - Display friend status via the isContact field.
3. Remark management - Use the remark field to display the current remark and modify it via the setUserRemark method.
4. Chat settings control - Use the isPinned and isMuted fields to control pin to top and do not disturb status.
5. Interactive operation - Implement set toggle via the setChatPinned and setChatMuted methods.
6. Status handling - Correctly handle the undefined status of fields to provide good user experience.
