fix(backend): FileServerServiceでレンジリクエストの場合に適切なレスポンスコードが返らない問題を修正 (#13701)

Browse source 
* return 206 for every ranged response - fixes #494

(cherry picked from commit 92eec2178f)

* detect size of remote files - fixes #494

without this, remote files are assumed to have size 0 (even if we just
downloaded them!) and the range-related code won't run

(cherry picked from commit 960f4fcff7)
