Refactor bot startup process to auto-create configuration files, enhance update system, and add historical stats endpoints

- Updated README.md to reflect new bot setup and configuration process.
- Removed outdated installer README and integrated update logic directly into the bot.
- Implemented smart update for example configuration files, ensuring user files are not overwritten.
- Added FileBootstrap class to handle automatic creation of configuration files on first run.
- Enhanced BotController to manage stop requests and ensure graceful shutdown.
- Introduced new stats management features, including historical stats and activity breakdown endpoints.
- Updated API routes to include new statistics retrieval functionalities.
