Refactor test modules and update test integration

Moved test-related code from src/gui/tests.rs to src/tests/run.rs and created a new src/tests module. Updated imports and module structure to reflect this change. Removed old cpu_tests.rs and added manual_tests.rs to run all emulator feature tests using the new test runner.
