Three small UIUX fixes for the workspace terminal status bar.
1. Status dots were hardcoded bg-green-500 / bg-yellow-500 /
bg-red-500 / bg-zinc-500 — semantic-token misses. Switched to
bg-good / bg-warm / bg-bad / bg-ink-soft so the colors flip with
the canvas-wide ramp instead of pinning Tailwind raw values.
2. Reconnect button used hardcoded text-blue-400 / hover:text-blue-300
with no focus ring. Switched to text-accent / hover:text-accent-strong
for theme parity, and added focus-visible:ring-accent/60 so
keyboard users see where focus lands on a recovery action.
3. Error banner used text-red-400 — switched to text-bad to match the
semantic ramp.
Status-bar bg/border kept as zinc (terminal body stays dark
unconditionally per the Canvas v4 design rule); only the chrome's
foreground tokens needed semanticisation.
