fix: 修复新建对话时因缺少会话ID导致配置绑定失败的问题 (#5292)

* fix:尝试修改

* fix:添加详细日志

* fix:进行详细修改，并添加日志

* fix:删除所有日志

* fix: 增加安全访问函数

- 给 localStorage 访问加了 try/catch + 可用性判断：dashboard/src/utils/chatConfigBinding.ts:13
- 新增 getFromLocalStorage/setToLocalStorage（在受限存储/无痕模式下异常时回退/忽略）
- getStoredDashboardUsername() / getStoredSelectedChatConfigId() 改为走安全读取：dashboard/src/utils/chatConfigBinding.ts:36       - 新增 setStoredSelectedChatConfigId()，写入失败静默忽略：dashboard/src/utils/chatConfigBinding.ts:44
- 把 ConfigSelector.vue 里直接 localStorage.getItem/setItem 全部替换为上述安全方法：dashboard/src/components/chat/ConfigSelector.vue:81
- 已重新跑过 pnpm run typecheck，通过。
