fix: request upload-authorized username hints

[TingRuDeng]

Problem

On Operations > File Transfer, the account username autocomplete called the shared hints endpoint without identifying the operation. Core could not distinguish an upload from the connect request used by Quick Jobs, so upload-specific permission filtering could not be applied.

Change

Send action: upload with the username-hints request. The companion Core change uses this value to return only accounts authorized for file upload. Older Core versions ignore the additional field.

Companion: jumpserver/jumpserver#17235
