feat(audit): log successful JWT auth with subject, acting_party, roles

- Add 'auth ok' info log after JWT validation passes
- Export ClaimString/ClaimStringSlice from identity package
- Log fields: subject, acting_party, roles/permissions, path, method
- Complements existing 'auth failed' error logs for full audit trail

-# Tekton Integration Tests
-
-Curl-based integration tests for the API gateway, orchestrated by Tekton.
-
-## How It Works
-
-```
-CI pushes image:sha → creates PipelineRun → Tekton spins up gateway sidecar
-→ runs curl tests → reports pass/fail → CI promotes to :latest if pass
-```
-
-The Task runs the gateway image as a **sidecar** (same pod, localhost),
-then executes `scripts/integration-test.sh` which tests every adapter
-via `X-Service` + `X-Resource` header routing.
-
-## Files
-
-| File | Purpose |
-|------|---------|
-| `task-integration-test.yaml` | Task: sidecar gateway + curl test step |
-| `pipeline-integration-test.yaml` | Pipeline: wraps the Task |
-| `scripts/integration-test.sh` | Test script (mounted as ConfigMap) |
-| `kustomization.yaml` | Generates ConfigMap from script |
-
-## Manual Run
-
-```bash
-kubectl apply -k k8s/tekton/
-kubectl create -f - <<'EOF'
-apiVersion: tekton.dev/v1
-kind: PipelineRun
-metadata:

-EOF
-
-# Watch
-kubectl logs -f -n api pipelinerun/integration-test-manual -c step-run-tests
-```
-
-## Updating Tests
-
-Edit `scripts/integration-test.sh`, then:
-
-```bash
-kubectl apply -k k8s/tekton/   # recreates ConfigMap
-```
-
-## Tekton Infrastructure
-
-Tekton Pipelines is installed in `~/workplace/homelab` via ArgoCD
-(`k8s/argocd/apps/06-ci-cd.yaml` → vendored `k8s/infra/tekton/release.yaml`).
