bump nodejs to 24

Update script:
- Replace aggressive rm + npm install --force with npm update -g n8n
  which is the official recommended way to update n8n
- Keep legacy migration (env file) and ensure_dependencies

Install script:
- Remove unnecessary build-essential, python3, python3-setuptools
  (n8n ships pre-built binaries, no native compilation needed)
- Remove ca-certificates (already provided by base image)
- Remove patch-package (not used)
- Use npm install -g instead of --global for consistency

Closes #12250
