Replaces the old "Up All / Server ▾ / Tunnel ▾" five-button grid with a
single power-toggle button (▶️ Start / 🛑 Stop) plus three flat-nav
buttons (Logs / Users / Refresh). Granular per-service control stays
reachable via the existing /server_up, /server_down, /pf_up, /pf_down
slash commands.
Message body redesigned: top-line health pill (🟢 Online / 🟡 Partial /
🔴 Offline), then aligned status rows for Server and Tunnel, then the
update timestamp. Uses the same 🟢/🔴 pair throughout for consistency,
dropping the mixed ✅/⛔ + 🟢/🟡 from before.
