Fix: Bundle Silero VAD model with PyInstaller

Fixed PyInstaller build error where the Voice Activity Detection (VAD)
model was missing from the compiled executable.

Changes:
- Added faster_whisper/assets folder to PyInstaller datas
- Includes silero_vad_v6.onnx (1.2MB) in the build
- Resolves ONNXRuntimeError on transcription start

Error fixed:
[ONNXRuntimeError] : 3 : NO_SUCHFILE : Load model from
.../faster_whisper/assets/silero_vad_v6.onnx failed: File doesn't exist
