test(ministack): add webhook to scale-up smoke chain

[edersonbrilhante]

Description

Add a MiniStack integration smoke test for the API Gateway to webhook, EventBridge, dispatcher, SQS, and scale-up path. The test starts a pinned mockserver/mockserver container with declarative GitHub API expectations and verifies the internal Lambda handoffs plus the three GitHub API calls.

Test Plan

• Local full MiniStack smoke test passed with the MockServer container.
• sh -n tests/ministack/run-smoke.sh
• python3 -m json.tool tests/ministack/github-api-expectations.json
• terraform fmt -check -recursive
• git diff --check
