Test encrypted native call history across Guardian reviews (#57474)

Browse Source 
## What changed

Extend the incremental Guardian review scenario with historical encrypted `send_message` calls in the default and custom tool namespaces. Add snapshots and assertions that both reviews retain each call and parent reply exactly once, in order, preserving call IDs, namespaces, and encryption metadata with a paired evidence-only output.

Verify that successive reviews reuse the same thread and append to the previous input. The scenarios use mocked ciphertext and decisions to check transport behavior, not backend decryption or authorization outcomes.

Scenario: A historical MAv2 send_message call and an encrypted parent reply reach both Guardian reviews exactly once, in order. Calls retain their original IDs, namespace and encryption metadata, with a paired evidence-only output. The second review appends to the first request. Ciphertext and decisions are mocked; this verifies transport, not backend decryption or authorization outcomes.
