refactor: Update DatabaseService to use settings_service for database URL

The DatabaseService class in service.py has been updated to use the settings_service object for retrieving the database URL instead of directly passing it as a parameter. This change improves code organization and ensures consistency with other services that rely on the settings_service. The necessary modifications have been made in both the DatabaseService class and the DatabaseServiceFactory class.
