feat: Implement quick commands import functionality with scripts and example JSON

This commit introduces two new scripts, `import-quick-commands.ps1` and `import-quick-commands.sh`, for importing quick commands into the NyaTerm database. It also adds an example JSON file, `quick-commands.import.example.json`, demonstrating the expected format for quick commands and categories. Additionally, a new Rust example, `import_quick_commands.rs`, is added to handle the import logic, including options for database path, replacement, dry run, and backup. This enhancement streamlines the process of managing quick commands within the application.
