Add dependency installation check and logging to deploy script

- Introduced `install_dependencies_if_needed` function to conditionally install dependencies based on the presence and changes in `package-lock.json`.
- Updated the deployment process to log build output to a file for better error tracking.
- Modified Nuxt configuration to disable source maps in production and prevent reporting of compressed sizes in Vite builds.
