frontend: dismissible chat error alert + compact import card

- the inline chat error now has an X to dismiss it, and is the single surface
  for errors (dropped the duplicate toast) so failures show once and clearly
- the import preview card caps the skipped-rows list (scrolls, one line each
  with a "+N more" tail) so a file full of validation errors no longer renders
  a giant card
