Add TED Scraper Configuration and Cron Scheduler Implementation

- Introduced a new configuration file for the TED scraper, defining database connection settings, logging preferences, and scraping parameters. - Implemented a CronScheduler to manage scheduled tasks for TED operations, utilizing the robfig/cron library for scheduling. - Added new entities and structures for handling TED XML data, including eForms and tender-related information, enhancing the scraper's functionality. - Updated the main application to initialize the TED scraper with the new configuration and set up graceful shutdown handling. - Removed the deprecated scraping implementation to streamline the codebase and focus on the new architecture.
