ibayueandClaude 3957b35809 feat(composer): add background color and clearer font-size button ...

- Background color toolbar button next to text color, using the
  BackgroundColor extension from @tiptap/extension-text-style (same
  textStyle-mark pattern as Color) with a 2x8 soft-tint highlighter
  palette and a remove action; emitted as inline
  style="background-color: …" which survives email round-trips.
- Font-size button now shows a big-A/small-A glyph (ALargeSmall) with
  the active size as a small badge, replacing the plain "Aa" text that
  was easy to miss.
- background_color/remove_background_color toolbar labels in all 24
  locales; unit tests for apply/unset/parse/coexistence with color and
  font-size on the same span.
