Steve G 9806e21871 Add Lakera v2 post-call hook and tests (fixed PII masking) (#21783)
* Add post-call hook for Lakera guardrail and mask PII in responses

* Add post-call hook for Lakera and mask PII in responses

* Fix post-call hook: pass event_type to call_v2_guard

* Address Greptile review: return ModelResponse, fix mutation, add header, test location, mask order

- PII masking path: return ModelResponse instead of dict so deployment hook accepts it
- Avoid mutating request data: deep copy original_messages and messages in _mask_pii_in_messages
- Add guardrail header in PII-only return path
- Add test in tests/test_litellm/ (test_lakera_ai_v2.py) per PR checklist
- Sort PII payload spans by (start,end) descending so multiple spans in one message mask correctly

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/test_litellm

This folder can only run mock tests.
