Implemented E2E test for clearing project from issue to none. **Changes made:** - Created tests/e2e/test_update_issue_clear_project_to_none.py with 5 test cases: 1. test_update_issue_clear_project_to_none - Basic clearing of project via 'No Project' option 2. test_update_issue_clear_project_and_verify_ui_update - UI state verification after clearing 3. test_update_issue_change_project_then_clear - Change project then clear workflow 4. test_update_issue_clear_project_dropdown_shows_no_project_option - Verify dropdown always shows 'No Project' option 5. test_update_issue_clear_project_identifier_not_changed - Verify identifier stability **Testing:** - Test file syntax verified with py_compile - Tests collected successfully by pytest (5 tests) - Follows same pattern as test_update_issue_clear_assignee_to_null.py **Verification:** - E2E tests require Docker which was not available in this environment - Tests should pass when run with make test-e2e in a Docker-enabled environment
