Ink's Output.get() calls .trimEnd() on each line of the rendered grid.
Without this, vue-tui's paint grid always fills the full root width with
spaces, causing raw frame output to contain 100-char-wide padding. This
broke tests using { raw: true } and made meaningful trailing-space
assertions impossible with { trimLines: true }.
Also corrects test assertions for 'set width in percent' and 'relative
position' that expected trailing spaces which Ink never produces.
