Add dual URL support for JellyStat - internal API, external posters

- Added optional Internal JellyStat URL setting for server-side API calls
- Backend now uses internal URL (e.g., http://192.168.80.77:3000) for API requests
- Frontend continues to use external URL (e.g., https://jellystat.glassnetworks.net) for poster images
- This resolves mixed content issues while maintaining SSL certificate compatibility
- If internal URL is not set, falls back to main URL for backwards compatibility
