* fix(callbacks): allow MAX_CALLBACKS override via env var (#20778)
* fix(callbacks): allow MAX_CALLBACKS override via env var
- Move MAX_CALLBACKS from logging_callback_manager.py to constants.py
- Add LITELLM_MAX_CALLBACKS env var override (default: 30)
- Add troubleshooting doc explaining the limit and override
Fixes issue where large deployments with 60+ teams using guardrails
would hit the hardcoded MAX_CALLBACKS=30 limit and fail to start.
* docs: add max_callbacks to sidebar navigation

* 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.
