test: add EDR passenger pricing/config E2E bug-hunt harness

Hermetic E2E harness targeting pricing integrity and backoffice config:
- e2e/ docker Postgres (5544) + prepare.sh/run.sh one-command runner + HTML report
- 6 suites / 23 tests reproducing pricing, FX, wallet, refund, config and auth
  defects (see docs/ISSUES.md); docs/e2e-test-matrix.md documents the matrix
- two-tier harness (slim module boot + direct service instantiation) to work
  around the IAM/RabbitMQ/file-type boot wall
- .env.test.example tracked; loader falls back to it for fresh checkouts
