feat: style Messages room-type labels as Concord-style pills

Render the "Public Chat" / "Marmot Group" (and the other room-type)
labels in the Messages list as a muted HeaderPill chip — the same faint
rounded chip the Concord community label uses — instead of plain gray
inline text, so every group kind reads the same way across the screen.
Each type gets a fitting icon (Public, Timer, Lock, Dns, Group).

Also rename the "MLS Group" label to "Marmot Group".
