`TableFooter` ships a corrupted class string

• Where: gem/lib/ruby_ui/table/table_footer.rb:13:
  "border-t bg-muted/50 font-medium[& amp;>tr]:last:border-b-0". The
  amp; is HTML-decoded text pasted into Ruby source; a space before [
  is also missing.
• Effect: every TableFooter emits the tokens font-medium[& and
  amp;>tr]:last:border-b-0 — neither is a Tailwind class, so font-medium
  and the last-row border rule are both lost.
• Fix: "border-t bg-muted/50 font-medium [&>tr]:last:border-b-0";
  re-record (on the 2.0 line) table/*.

Surfaced by the golden HTML suite (PR #536), which pins what 1.6 renders today — this defect included. Per maintainer decision (2026-09-19) main stays as is: this is addressed on the 2.0 line, and the golden snapshot that pins it is re-recorded there with the diff reviewed.

Beginne bei gem/lib/ruby_ui/table/table_footer.rb:13 und prüfe die Zeichenkette der Klasse TableFooter anhand der im Issue erwarteten Tokens. Führe auf der 2.0-Linie die golden-HTML-Suite aus, zeichne table/* erneut auf und prüfe den Diff; fertig bedeutet, dass die korrigierten Klassen und geprüften Snapshots vorhanden sind, ohne main zu ändern.
