* fix(guardrails): return the full PANW AIRS scan response on blocked requests
The blocked-request error detail was assembled from a hardcoded allowlist, so audit fields like prompt_detection_details, prompt_masked_data, source, transaction_id and session_id never reached the client even though AIRS returned them.
Resolves LIT-5638

* fix(panw_prisma_airs): withhold response_masked_data from the blocked-response error
The full AIRS passthrough also reached the response-side block path, where
response_masked_data carries the model's own generation. That branch is only
reached when mask_response_content is False, so the operator had explicitly
declined to deliver that text, and the error body handed it back anyway.
Withhold response_masked_data from the client-visible detail. prompt_masked_data
stays: it is the caller's own input and one of the fields the ticket asks for.
Every other AIRS field, including prompt_detection_details, source,
transaction_id and session_id, is unchanged.
* fix(panw_prisma_airs): withhold generated tool args from response-side blocks
_scan_tool_calls_for_guardrail calls AIRS with is_response=False because
tool_event is request-side in the AIRS schema, so AIRS returns the scanned
tool arguments under prompt_masked_data. When the tool calls being scanned
are the model's own output, that key holds generated content, and the
_CLIENT_HIDDEN_SCAN_FIELDS default (response_masked_data, empty on this
path) does not cover it. With the default mask_response_content=False the
block branch then shipped the model's masked tool arguments in the 400 --
the same content channel this PR closed for response_masked_data.
_build_error_detail takes an extra_hidden_fields argument so the withholding
stays in one place, and the tool-call block branch passes prompt_masked_data
when is_response is True. Request-side blocks are unchanged and still carry
prompt_masked_data, which is what LIT-5638 asks for.
