Implement Scraper Dockerfile and Refactor CI Configuration

- Added a new Dockerfile for the scraper application located at cmd/scraper/Dockerfile to streamline the build process.
- Updated the CI configuration in .drone.yml to correctly build the scraper application with the new Dockerfile.
- Refactored the main application entry point to utilize a new bootstrap package for configuration, logging, and MongoDB initialization.
- Enhanced the scraper's configuration management by defining a dedicated Config struct for better organization and maintainability.
