Add AI-assisted QA test workflow: scenario cards, runner, hooks, API capture

A complete loop for defining, generating, running and gating tests:

- qa/: scenario-card template + examples (API/UI/binding), the Claude
  generation prompt, and a QA runbook tying it together
- e2e/CLAUDE.md: conventions that keep AI-generated tests consistent
- run-tests.ps1: one runner for every layer (backend/api/web/ui/binding),
  logs per run under .testlogs/, JUnit output, evidence report, and a
  re-seed guard against stale demo data
- .githooks/ + scripts/install-hooks.ps1: pre-commit secret scan and
  pre-push unit tests (shift-left before CI)
- evidence report now captures each API call's request, payload and
  response (Authorization redacted); JUnit reporter added for CI
- scripts/db.mjs: db:check freshness guard

Azure DevOps pipeline deferred; the runner already emits JUnit + the
evidence report for any CI to publish.
