Deleted `CommonBirbankScript` and its associated derived classes (`GetLastDaysHistoryBirbankScript`, `LoginAndCheckAccountsBirbankScript`, `PayByCardBirbankScript`). Removed dependencies on these scripts, including XML parsing, account handling, and transaction workflows related to the Birbank app.
Removed redundant "numbers" field from Account model and database queries to simplify account structure. Introduced a TutorialWindow class for displaying application tutorials, integrated into the main window, and updated file paths accordingly. Improved string handling and logic in Payment routines and enhanced overall UI structure.
