Chat chrome ends at the rail with a rounded corner

Docking the two chat bands into the rail card removed the floating cut
but the edge stayed a straight vertical line - still a seam ("this
still looks bad"). Both bands now keep the rail's own 12px gutter and
end in the rail card's 1.5rem radius on their left side, so the ending
reads as deliberate; the header divider spans the flat part of the
bottom edge, from the corner curve inward. Phones keep the plain
full-width borders.

The chat suite now pins the geometry: 12px gutter at the seam, 24px
left corners on both bands, zeroed band borders, inset ::after
hairlines. Chat 104/104, mobile 126/126, regression 50/50.

Version 0.5.7, SW -> freezmo-v79.
