feat(test-env): add 1C test environment (#11)

* feat(test-env): add 1C test environment manifests (#11)

- PostgreSQL 18.x-2.1C StatefulSet with ru_RU.UTF-8 locale init
- 1C server (ragent+crserver+ras) StatefulSet with stable hostname
- Gitea runner Deployment with edt label for apk-ci-ng
- NodePort services for external 1C access (31540-31545)
- Deploy/verify script: dev/deploy-test-env.sh
- config.yaml for ApplicationSet integration
- test-env only in dev cluster (not in prod AppSet)

* fix(test-env): use initContainer for PG data + remove custom entrypoint

PVC mount on /var/lib/postgresql wipes the image's pre-built cluster.
Solution: initContainer copies cluster data from image to PVC on first run.
Removed custom pg-entrypoint.sh ConfigMap — image has its own.

* feat(test-env): DinD sidecar for runner + auto-registration Job

- Add Docker-in-Docker sidecar to gitea-runner Deployment
- Add register-job.yaml: Job that obtains Gitea runner token via API,
  creates Secret, and scales runner to 1
- RBAC: ServiceAccount + Role/ClusterRole for cross-namespace secret access
- Runner labels: edt (for apk-ci-ng), ubuntu-latest

+# PostgreSQL ConfigMap
+# The benadis/pg-1c image has a built-in entrypoint that:
+#   1. Configures postgresql.conf with 1C optimizations on first run
+#   2. Sets pg_hba.conf for network access
+#   3. Creates usr1cv8 superuser
+#   4. Starts PostgreSQL
+#
+# No additional configuration needed — all settings are baked into the image.
+# This file is kept as documentation placeholder.
+# If custom settings are needed in the future, mount them via ConfigMap.
