* Fix spend logs pickle error with Pydantic models

Replace copy.deepcopy() with Pydantic-safe serialization to avoid
"cannot pickle '_thread.RLock' object" errors when request/response
redaction is enabled.

Changes:
- Add _convert_to_json_serializable_dict() helper that uses
  model_dump() for Pydantic models instead of pickle
- Replace copy.deepcopy() calls in request and response redaction
  paths with the new helper function
- Recursively handles nested dicts, lists, and Pydantic models

Root cause: Pydantic v2 BaseModel instances contain internal
_thread.RLock objects for thread-safety. When copy.deepcopy()
attempts to pickle these objects, it fails because threading
primitives cannot be pickled.

Fixes #20647

* chore: remove unused copy import

Remove unused copy import that was causing lint failure. The copy.deepcopy()
calls were replaced with _convert_to_json_serializable_dict() helper function
in the previous commit, making the copy module no longer needed.
