Component integration tests

### Feature Summary

New integrationTests/components/ directory. Single node: deploy component from GitHub, seed data, hit endpoints, assert responses. Runs on PR + merge to main. Covers the functional logic layer for all five components:

- [ ] risk-query
- [ ] redirector
- [ ] early-hints
- [ ] acl-connect
- [ ] ecommerce-template

### Problem This Solves

Component regressions are currently caught through manual QA. These tests automate that coverage so breakages in core Harper that affect components are caught in CI before they reach production.

### Proposed Solution

One test file per component in `integrationTests/components/`. Each test uses `harperLifecycle.ts` to start a local harper instance, deploys the component via `deploy_component` , polls until ready, runs functional assertions against the HTTP API.

### Priority/Impact

High - critical for user success
