Implement optional sorting of programming languages

Add user preference for programming language sorting with the following features:
- New database field 'programming_languages_sorted' (defaults to True for backward compatibility)
- Commands to enable/disable sorting: 'сортировать'/'sort' and 'не сортировать'/'no sort'
- Updated info message to show sorting status for current user
- Updated data builder to respect user's sorting preference
- Added comprehensive tests for the new functionality

Users can now choose whether their programming languages are displayed sorted alphabetically or in the order they were added.
