fix: resolve CI/CD linting and formatting issues

- Replaced deprecated typing.Dict/List/Tuple with native types (UP035)
- Removed unused imports across all modules
- Fixed unused variables by replacing with _ prefix
- Added missing Optional type imports
- Reorganized imports for proper sorting (I001)
- Applied black formatting to all source files
