- Add missing `solution` field to solution-type nodes in test tree structures
(required by `can_publish_tree` validation for published trees)
- Fix `AsyncClient(app=...)` → `ASGITransport(app=...)` in test_save_session_as_tree
(httpx deprecated the `app` parameter in favor of transport)
- All 189 tests now pass (was 84 passed, 1 failed)
Files fixed: conftest.py, test_permissions_account.py, test_subscription_limits.py,
test_trees.py, test_save_session_as_tree.py
