feat: add NFS server and Transmission service to sleeper-service

- Created modules/services/nfs.nix for network file sharing
- Updated sleeper-service configuration with NFS and Transmission
- Fixed SSH key management to use direct key configuration
- Updated hardware-configuration to use sleeper-service hostname
- Added firewall ports for Transmission RPC (9091)
