fix: precise chat layout alignment to match Aether Drift prototype

Message rows: 20px horizontal padding, 3px vertical, 56px avatar column,
subtle 2.5% hover. Channel headers: border instead of shadow, text # hash,
10px gap, 6px button radius. Date dividers: 8px margin, 11px text, border-hard
lines. Input bubble: 34px buttons with 18px SVGs, 10px textarea padding.
Inline code: lavender on #111115 with border-soft border.
