重构: 前端架构审查降技术债·i18n收口(高ROI)

- 新建 src/i18n/i18n-helpers.ts: 类型安全 t + currentLocale(any中转内部1处带注释)
- 12文件改 i18n as any 样板收口: utils/time + stores(knowledge/project/{ideas,projects,tasks,workflow}) + composables(aiShared/useAiConversations/useAiEvents/useAiSend/useAiStream/useToolCard)
- as any 22→10(i18n 13→0对外), 签名统一(key, named?)
- useToolCard文档块同步(防AI被过时注释误导)
