Make the sync result look right with any number of columns

- Visible columns share the width equally, whether one or five are shown
- Long soundtrack names and errors wrap inside their column instead of
  widening the window, which pushed the title and Restart button out of
  view and cut off text
- Separators only go between columns; the extra one before the first
  column is gone
- Wider, centred panel with inner margins, and spacing above the
  Restart button
- The Re-added header no longer reads ReAdded
