Refactor and enhance database and form operations

Significant changes have been implemented in the database operations, particularly in update and insert functions, ensuring more stable and efficient handling of queries. Form capabilities have been enhanced by adding new attributes for processing decimal steps, further improving data input methods. This update also includes considerable refactoring and security enhancements in the PDO class.
