Address reviewer feedback: Fix MinIO endpoint and add admin permissions

- Fix MinIO endpoint configuration to use SERVICE_URL_MINIO_3200 for public access
  This resolves the issue with signed URLs for photo uploads as noted by @devdilson
- Add ENTE_INTERNAL_ADMIN environment variable to grant first account admin permissions
  This prevents the 10GB storage limit issue mentioned in the review
- Update service templates JSON files with the corrected configuration
- Ensure MinIO service has proper SERVICE_URL configuration for external access

Addresses all feedback from @devdilson's review comments:
- Fixes signed URL access for photo uploads
- Grants admin permissions to first account
- Maintains proper service architecture for Coolify deployment
