A plain <a> file download can't send the X-Siftlode-Account header, so current_user resolved
it to the session-default account — 404 'Unknown download' when the tab acts as a non-default
wallet account that owns the file. resolved_user_id now also honours a ?account= query param
(the same wallet-gated selection the WebSocket already uses), and downloadFileUrl appends the
active account id. Verified: default account -> 404, ?account=<owner> -> 206 with the right
Content-Disposition.
