TPT-4731: Fix nested CLI arguments for schemas without an explicit type

[zliang-akamai]

📝 Description

Expand nested request arguments and response attributes for composed schemas without an explicit type: object, fixing flags such as --details.host. Preserve JSON-formatted fields and explicit scalar/array handling, with regression coverage.

✔️ How to Test

Focused regression tests:

 python -m pytest tests/unit/test_request.py tests/unit/test_response.py -k test_handle_one_ofs -k test_explicit_non_object_composed_schema -k test_json_format_composed_objects

Command it fixes:

Creating a bucket in us-mia with an OBJ key with read/write access to the bucket first.

linode-cli streams destination-create --label test-stream-def --type akamai_object_storage --details.host <YOUR_OBJ_BUCKET>.us-mia-1.linodeobjects.com --details.bucket_name <YOUR_OBJ_BUCKET> --details.path audit-logs --details.access_key_id <YOUR_OBJ_KEY_ID> --details.access_key_secret <YOUR_OBJ_KEY>
