When the setup script detects TEMPERATURE_PROXY_KEY (proxy is available),
it now shows a clear success message instead of attempting SSH verification.
The verification check doesn't work with proxy-based setups since the
container doesn't have SSH keys - all temperature collection happens via
the Unix socket to pulse-sensor-proxy, which handles SSH.
Now shows:
✓ Temperature monitoring configured via pulse-sensor-proxy
Temperature data will appear in the dashboard within 10 seconds
Instead of the misleading:
⚠️ Unable to verify SSH connectivity.
Temperature data will appear once SSH connectivity is configured.
