Fix S3 configuration - set are_local_buckets to true

- Changed are_local_buckets from false to true (required for external S3)
- Simplified S3 configuration to only use b2-eu-cen bucket
- Removed unnecessary replication buckets for single bucket setup

This aligns with Ente's documentation where are_local_buckets=true
is used for external S3 services like Wasabi.
