Fix sensitive_data_leakage tool context not reaching agent callback in Foundry path (#46151)

* Fix sensitive_data_leakage tool context not reaching target in Foundry path

In the Foundry execution path, agent-specific context items (with tool_name
fields like document_client_smode) were stored in SeedObjective.metadata but
PyRIT discards SeedObjective.metadata during attack execution -- only
objective.value is sent to the target. The target never saw the sensitive
data, causing all sensitive_data_leakage objectives to score 0.0.

Fix by creating context as SeedPrompt objects at lower sequence numbers so
PyRIT places them in prepended_conversation (conversation history). A user
SeedPrompt for the objective text is added at a higher sequence so it becomes
next_message (the actual prompt). _CallbackChatTarget filters these context
pieces out of the messages list (so the model doesn't see raw sensitive data
as prior user messages) and instead reconstructs context['contexts'] with
tool_name fields. This enables the ACA runtime agent_callback to build
FunctionTool injections without any changes to the ACA code -- the model
must call the tool to access the sensitive data, matching the intended
attack semantics.

* Fix SDL seed risk-type, memory fixture, add changelog

- Use underscores in risk-type ('sensitive_data_leakage') to match SDK
  validator. The service uses hyphens but the SDK expects underscores;
  seeds with hyphens were silently skipped, leaving no tool-context
  objectives in the test.
- Wrap CentralMemory.get_memory_instance() in try/except since it throws
  if called before any instance is set.
- Add CHANGELOG entry for 1.16.5.
- Merge upstream main.

* Add 'smode' to cspell ignoreWords

The tool names document_client_smode and email_client_smode come from the
RAI service's attack objectives for sensitive_data_leakage.

* Fix conversation contamination between Foundry E2E tests

- Reset PyRIT database (drop/recreate tables) before each test instead of
  using :memory: DB that gets overwritten by RedTeam.__init__
- Filter is_context pieces in FoundryResultProcessor._build_messages_from_pieces
  so context SeedPrompts don't appear as extra user messages in conversations

* Use strict is_context check to avoid MagicMock false positives

Use isinstance(pm, dict) and pm.get('is_context') is True instead of
truthy checks. MagicMock objects return truthy values for any attribute
access, causing all conversation pieces to be filtered out in unit tests.

 ### Bugs Fixed
 
+- Fixed `sensitive_data_leakage` risk category producing 0% attack success rate (false negatives) in the Foundry execution path. Agent-specific tool context (e.g., `document_client_smode`, `email_client_smode`) was stored in `SeedObjective.metadata` but never propagated to the target callback, so the agent could not access the sensitive data it was supposed to leak. Context is now delivered via `prepended_conversation` SeedPrompts and extracted from conversation history metadata, enabling the ACA runtime to build FunctionTool injections.
 - Fixed multi-turn and crescendo red team strategies producing output items identical to their baseline counterparts. The Foundry execution path was writing all strategies' conversations to a single shared JSONL file, causing each strategy to read all conversations and mislabel them. Now writes per-strategy JSONL files using PyRIT's scenario result grouping.
