Improve Node.js upgrade and service recovery in update.sh

Enhances the Node.js upgrade process by handling both .list and .sources files, updating the apt cache, and adding error handling for download and install failures. Introduces a function to re-enable and start the systemd service on failure to prevent user lockout, and ensures this is called during rollback and upgrade errors. Also refines Node.js version checks and build environment setup.
