fix: update integration test deps and skip LFS smudge in CI

- Upgrade event-ingester-service to v0.1.1-0.20260403130541-5bd52e351584
  which migrates large testdata to LFS, keeping the Go module zip under
  the 524 MB limit
- Upgrade postgres-connector to v0.0.1296 to align with utils-k8s-go
  API changes (NetworkPolicyPodSelectorMatchLabels)
- Set GIT_LFS_SKIP_SMUDGE=1 in CI so go mod download receives LFS
  pointer files instead of smudged content, preventing the zip size
  limit from being hit during module download
