refactor: 替换服务端 console.log/error 为 winston logger

- folder-action.ts: 18处 console.log -> log.error
- auth-action.ts: 4处 console.error -> log.error
- dictionary-action/service.ts: 3处 -> log.error
- translator-action/service.ts: 3处 -> log.error
- bigmodel/translator/orchestrator.ts: console -> log.debug/info/error
- bigmodel/tts.ts: console -> log.error/warn
- bigmodel/dictionary/*.ts: console -> log.error/debug/info

客户端代码（browser、page.tsx）保留 console.error
