🔧 Add PowerShell script for Bitwarden .env synchronization

- Introduced `sync-env.ps1` to facilitate the synchronization of environment variables from Bitwarden on Windows.
- Implemented checks for Bitwarden CLI installation and authentication status.
- Added functionality to fetch environment variables from a specified Bitwarden item and create/update a `.env` file.
- Enhanced user feedback with clear error messages and success confirmations.

✅ This script streamlines the management of environment variables by integrating with Bitwarden, ensuring secure and efficient updates.
