fix(ui): collapse PTT badge to single folds Chip (N53); responsive bg pickers (N81)

N53: removed the duplicate lotusTerminal PTT-badge branch (raw <Box> with
--lt-* vars + bespoke rem/animation styling). The standard folds <Chip>
path now renders in all modes; TDS theming still flows through the CSS var
layer. Dropped the now-unused lotusTerminal read.

N81: ChatBgGrid / SeasonalBgGrid containers switched from flex-wrap with
fixed-width cells to a responsive CSS grid (repeat(auto-fill, minmax(76px,
1fr))), so swatches fill the row evenly instead of orphaning a lopsided
last row at arbitrary widths.
