feat(hooks): use ZENABLE_NONINTERACTIVE and simplify post-gen hook

Replace ZENABLE_YES with ZENABLE_NONINTERACTIVE env var for clarity.
The installer scripts now handle integrations in non-interactive mode,
so remove the post-install PATH manipulation and second binary lookup.
When zenable is already installed, pass -y to zenable install.
