feat(tui): clear the whole queue from the transfers pane

Shift-C in the Downloads/Uploads pane now cancels every live download,
forgets every row — queued, finished or failed — in the session too,
and cancels uploads still streaming, so a shared queue empties for
every window at once. The existing c keeps clearing only finished
transfers.
