test: real integration tests for X-Service adapter routing

Tests that verify actual service operations:
- SQS send-message routing
- S3 list-objects with JWT pass-through
- Memory query routing
- IAM with JWT
- Authorization header pass-through to services

Tests gracefully skip if services unreachable (expected behavior).
Tests get real JWT from Authentik if credentials provided.
