Fix environment variable handling in SSH execution

- Environment variables are now properly exported in SSH session
- Support both comma-separated and newline-separated format
- Fixed parsing to handle all environment variables correctly
- Added debug output to help troubleshoot issues
- Environment variables are set at the beginning of the script execution
- Added script preview to show what will be executed

This should resolve the issue where only 1 environment variable
was being set instead of all 4 provided.
