fix(tui): use lipgloss.Width in padRight/padLeft and split embedded newlines in addLog

- padRight/padLeft used len(s) which counts ANSI escape bytes as visible chars.
  Styled strings (accentStyle, warnStyle...) had len >> visual width, causing
  the status/version/source columns to overflow into description → columns gone.
  Fixed by using lipgloss.Width() for measurement and truncate() for cutting.

- addLog stored Nuxt multi-line chunks as a single logLines entry. The panel
  height calculation counted 1 line but the renderer produced N lines via the
  embedded \n → panel exceeded allocated height → wave/surf scroll effect.
  Fixed by splitting on \n before storing, skipping empty sub-lines.
