patrick 96789620bb feat: run book uploads in a background tray
One request per book instead of one for everything, queued in state above the
dialog so closing it no longer cancels the import. A docked tray reports each
book and offers a retry; it clears itself after a clean run, stays put if
anything failed, and holds while hovered.

Also fixes the dialog overflowing on long filenames — Dialog.Content is a grid
and its body needed min-w-0 to shrink below the content's intrinsic width.

content's intrinsic width, so one long name widened the body and pushed it
straight through the dialog's edge regardless of any truncate further down.
