Jordan Ritter 811afa9025 fix(showcase): ms-agent-dotnet D6 residuals (toolCallId strip, fixtures, hitl pages)
Address the four residual D6 failures on the ms-agent-dotnet integration
(baseline was 177/5).

route.ts toolCallId strip completeness
- Extend stripReplaySafeToolCallIdsFromMessage to also clean the
  snake_case `tool_calls[].id` array and any nested OpenAI-style
  `function.tool_call_id`. AG-UI canonical uses `toolCalls`, but some
  runtime / message-converter paths emit the OpenAI shape and the
  replay-safe `__ck_run_<uuid>` suffix was leaking through to aimock on
  those paths. Apply the same coverage in applyToolResultDecisionSuffix
  so decision-suffix routing (`__approved` / `__rejected` /
  `__cancelled`) lands on every tool-call shape.
- Add a universal strip middleware in createAgent itself so EVERY
  registered agent (not only the replay-safe ones) clears the suffix
  before the request reaches the backend / aimock. Decision suffixing
  remains scoped to createReplaySafeAgent because the suffix is
  non-idempotent and the inner middleware re-runs the same logic.
- Drop the now-redundant strip calls inside createGenUiAgent,
  createReadonlyContextAgent, createSharedStateReadWriteAgent, and
  createReasoningAgent — the outer createAgent middleware already
  canonicalised inbound messages by the time these run.

chat-slots fixture
- Mirror LGP's turnIndex:1 'Give me a fun fact' entry so the
  chat-slots e2e's second-turn assistant slot has a deterministic
  reply (the bare 'Give me a fun fact' fixture in headless-simple.json
  is turnIndex:0-gated and was never matching chat-slots' turn 1).

HITL reject + interrupt-headless cancel branches
- Add a reject-branch fixture in render-a2ui.json keyed on
  toolCallId `call_d5_generate_steps_001__rejected` so the hitl.spec
  reject-flow's 'will not execute the Mars trip plan' assertion lands
  the right narration. Keep the legacy hasToolResult:true fixture as a
  fallback for paths that don't apply a decision suffix. Add an
  `__approved` variant for symmetry.
- Add cancel-branch fixtures in interrupt-headless.json for both the
  sales-intro and 1:1-with-alice pills, keyed on `__cancelled`
  toolCallIds, returning the Denied/not-booked narration the
  interrupt-headless cancel spec expects.

hitl-in-app + hitl-in-chat demo pages already mirror LGP (only an extra
README.md per directory in this integration), so no page changes were
needed.
