feat: Add comprehensive test coverage for delete_objects_recursive()
- Add 19 thorough tests for client.delete_objects_recursive() method - Test delta suffix handling, error/warning aggregation, statistics - Test edge cases and boundary conditions - Fix mypy type errors using cast() for dict.get() return values - Refactor client models and delete helpers into separate modules All tests passing (99 integration/unit tests) All quality checks passing (mypy, ruff) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
