- Updated DbHandler to accept configuration parameters instead of using environment variables directly. - Moved database queries from handler.go to a dedicated queries package for better organization and separation of concerns. - Implemented error handling in query functions to provide more informative error messages. - Refactored image handling to utilize the new queries package for database interactions. - Cleaned up unused code and comments across various files. - Improved overall code readability and maintainability.
