fix: Resolve protobuf dependency conflict for pyannote.audio 4.x

- Update protobuf from <5.0.0 to >=5.0.0 (required by opentelemetry-proto)
- Update streamlit minimum version to >=1.30.0 (protobuf 5.x compatible)
- Update regular Dockerfile to match GPU dockerfile structure
- Install PyTorch CPU version in regular Dockerfile for consistency
