Egor fureunoir Gorbunov a81f734e23 Features: (1) None;
Fixes: (1) Removed all `# type: ignore` annotations across the codebase; (2) Fixed usage of Django Model methods by eliminating unnecessary `# type: ignore` directives; (3) Adjusted usage of functions like `get()` to align with method expectations, removing incorrect comments;

Extra: (1) Deleted `pyrightconfig.json` as part of migration to a stricter type-checked environment; (2) Minor code cleanup, including formatting changes and refactoring import statements in adherence to PEP8 recommendations.
