Enhance setup scripts for TTS environment initialization

- Updated setup.ps1 and setup.sh to check for and install the 'uv' package manager if not already present.
- Modified virtual environment creation to use 'uv' for consistency across platforms.
- Improved activation instructions for the virtual environment in both scripts.
- Added FFmpeg installation for Windows and system dependencies for Linux and macOS to ensure all necessary tools are available for TTS functionality.
- Streamlined dependency installation process to utilize 'uv' for package management.
