refactor: 句子历史记录收敛到 SentenceService，AI 翻译写库留历史

将 SentenceController 的私有 saveHistory() 迁入 SentenceService，
统一句子保存与历史记录入口；UpgradeAITranslation 写库改用 saveWithHistory，
AI 翻译结果现在也会留下编辑历史（此前 AI 写库不记历史）。

- SentenceService::save() 改为返回保存后的 Sentence，便于组合
- SentenceService 新增 saveHistory()（自控制器迁入，签名不变）
- SentenceService 新增 saveWithHistory()：save() 后用持久化句子写一条历史
- SentenceController 注入 SentenceService，4 处调用改走服务，移除私有方法与无用 import
- UpgradeAITranslation::save 循环改用 saveWithHistory
