fix(lipsync): 修复 GET /jobs/{id} 轮询 500（naive/aware datetime 减法 TypeError）

Postgres TIMESTAMP WITHOUT TIMEZONE 返回 naive datetime，路由层
(_now - job.updated_at).total_seconds() 抛 TypeError: can't subtract
offset-naive and offset-aware datetimes，被全局异常 handler 吞为 500
INTERNAL_ERROR，前端持续轮询一直报错。

修复：比较前把 naive datetime 当作 UTC wall clock 补 tzinfo（与代码写入
default=datetime.now(UTC) 一致），补 2 个单测覆盖 naive stale/fresh 两个分支。
176 tests passed.
