Chris Lu 7c5296dfb1 fix(admin): switch file browser upload/download to filer gRPC + volume HTTP (#9538)
* fix(admin): switch file browser upload/download to filer gRPC + volume HTTP

The admin file browser proxied uploads and downloads through the filer's
HTTP listener, so the whole feature 404'd against filers started with
-disableHttp=true even though S3 still worked on its own port. Re-route
through the filer gRPC service: LookupDirectoryEntry + StreamContent for
reads (chunks flow straight from the volume servers), AssignVolume +
volume HTTP POST + CreateEntry for writes. Volume read tokens come from
jwt.signing.read.key when configured; the old jwt.filer_signing tokens
no longer apply since the filer HTTP surface is bypassed.

* admin file browser: propagate request context + track response writes

Pass r.Context() into uploadFileToFiler so a client disconnect cancels
the in-flight chunked upload instead of letting it run to completion
against the volume servers. For DownloadFile, replace the Content-Type
probe with a small response-writer wrapper that records whether headers
or bytes have actually been sent, so the error path can't silently
convert a pre-stream failure into a partial response if future code
moves the header-setting around.
