feat: Add comprehensive ROCm GPU support for transcription and diarization

- Use ROCm-compatible CTranslate2 fork when ROCm hardware is detected - Map 'rocm' device to 'cuda' for faster-whisper compatibility - Add configurable GPU architecture support (RDNA2/RDNA3) - Improve ROCm detection with fallback mechanisms - Update Docker configurations with proper environment variables - Add debugging and setup scripts for troubleshooting ROCm issues This resolves the 'unsupported device rocm' error and enables full AMD GPU acceleration for both transcription and speaker diarization workflows while maintaining backward compatibility with CUDA and CPU devices.
