Fix JellyStat test connection permissions for iframe mode

- Modified jellystatHomepagePermissions to dynamically check display mode
- Iframe mode now only requires jellyStatURL (not API key)
- Native mode still requires both jellyStatURL and jellyStatApikey
- Resolves 500 Internal Server Error on JellyStat test connection
- Fixes overly restrictive permission requirements blocking iframe mode testing
