fix(ui): supersede settled import errors on every payload edit

File selection, conflict rename/confirm/skip, adapter overrides and
config, and continue-without-attachments all shape the next import
request but did not clear a settled failure, so the persistent panel
could keep describing a superseded request. Route them all through the
settled-state reset (pending requests remain untouched), and cover the
file-selection case in the component tests.
