fix(api): accept agent media type values

9 处裸构造 MediaType(x) 改为 MediaType.from_agent(x) or MediaType(x)，与 search.py/site.py 既有写法一致。智能体按 API 入参规约传入 movie/tv/music 时不再抛 ValueError 返回 500，中文原生枚举值仍走原分支，无行为变化。

涉及：media.py detail、tmdb.py(3)、douban.py(2)、mediaserver.py not_exists、subscribe.py create_subscribe、transfer.py _execute_manual_transfer。
