Enhance configuration and logging setup

- Added Microsoft.Extensions.Configuration.Json and Serilog.Settings.Configuration packages.
- Configured Serilog to read settings from appsettings.json.
- Updated .gitignore to exclude database and upload files.
- Refactored MainWindow to improve key handling and menu structure.
- Introduced appsettings.example.json for logging configuration.
