copy: second-round copy review across console, settings, agent and server messages

- Trim descriptions, empty states, confirm buttons and toasts to facts
- Unify terms per glossary: 待处理/待识别/整理记录/运行记录/凭证/子会话/Agent 上游
- Subscription-login termsNote states facts only (borrowed client identity, ToS/ban risk)
- Shorter, concrete goal templates for built-in Agent checks
- Human-readable nouns instead of table names in instance CRUD errors
- Audit labels for pi_upstream / schedule / automation_grant actions
- Glossary: add 上游、订阅登录、凭证、定时任务、巡检、运行记录、子会话、停止、持续授权
