fix: 修复所有页面 loading 动画未正确移除的问题

- chat-debug.js: loadDebugInfo 完成后正确调用 renderDebugInfo 移除 loading
- agents.js: loadAgents 失败时显示错误信息替代 loading
- dashboard.js: renderLogs 无日志时显示提示信息
- memory.js: loadFiles 失败时显示错误信息
- services.js: loadServices/loadRegistry/loadBackups 添加 loading 状态并在完成/失败时移除
- extensions.js: loadCftunnel/loadClawapp 添加 loading 状态并在完成/失败时移除
- models.js: loadConfig 添加 loading 状态并在失败时显示错误
- gateway.js: loadConfig 添加 loading 状态并在失败时显示错误
- logs.js: loadLog/searchLog 使用 loading-text 样式并在失败时显示错误

确保所有异步加载函数都：
1. 开始时显示 loading 状态
2. 成功时渲染数据（自动移除 loading）
3. 失败时显示错误信息（替代 loading）
