Map the unsupported Node version to the 22.12 minimum in the connection-test result.

For Node 22.11, the probe now throws at apps/server/src/device/sshDeviceScript.ts:143. sshProbeFailureMessage in apps/server/src/device/DeviceService.ts (lines 91-113) returns a specific message only for the Node-missing PATH diagnostic. Any other probe failure falls through to the generic device host check failed (exit code N) message. The 22.12 requirement does not reach the user.

Add an explicit classification for this rejection. Match a fixed diagnostic from the probe output, and return a fixed message that names the Node 22.12 minimum. Do not pass remote stderr through. The probe throws an Error, so its stderr can include a stack trace. Match the message text within a line, not the whole trimmed line. Cover the translated result in the existing service tests.

Review comment at @apps/server/src/device/sshDeviceScript.ts at line 143:
The Node 22.12 minimum rejection is reported as a generic connection-test failure. Update sshProbeFailureMessage to recognize the probe’s fixed minimum-version diagnostic within an output line and return a fixed user-facing message naming Node 22.12; do not expose remote stderr or stack traces. Add coverage for this translated result in the existing DeviceService tests.
