feat(web): 智能体会话去噪——单一免责、短标题、技术信息折叠(DEAI-2)

- 「未经核查」只在最终汇报左栏标题保留一处,删「仅供参考」与数据来源说明;
  右栏改叫「实际结果」,去掉「运行已完成」「工具成功 N」徽章,计数只列非零项,
  状态值用中文标签,不再显示计划 / 记录短 ID
- 工具卡片只标会改数据的动作和中高风险;能力 ID、scope、幂等、耗时、调用 ID、
  schema 入口收进技术信息;拒绝说明改成一句「要你批准」
- 用量只显示费用与时长,工具调用数、token、模型、会话 ID 进技术信息(超限时照常显示)
- 会话标题 shortGoalTitle:去上下文前缀、UUID、JSON 参数,能力 ID 换中文名,取第一句,40 字截断
- 入口去口号:删「交代目标，边做边汇报」与抽屉里的重复快捷键说明
- 对话组件结构不动
