feat(tui): tidy the welcome banner and status line

Carry the calmer transcript aesthetic through the rest of the chrome: the
welcome's three-line hint blob becomes a scannable two-row shortcut grid
with a single tagline, and the status line lifts the model name out of
the all-dim meta string so the thing you glance at most reads as the
anchor.
