Add relay hints when opening file events for download

Pass relay hints from the release event's seen relays when opening
file metadata events (kind 1063) for download. This ensures the
event loader knows where to fetch the file event from.

Also adds relay hints to the ReleaseItem component for both opening
the release detail and the download file.
