refactor(tikv/copr-test): migrate  images to cloud-accessible registries (#4322)

The tikv/copr-test pipeline referenced hub.pingcap.net (PingCAP internal
registry) for container images and OCI artifact downloads, making it
inaccessible from cloud environments.

## Changes

- **`pod-pull_integration_test.yaml`**
- `hub.pingcap.net/jenkins/rocky8_golang-1.23:latest` →
`ghcr.io/pingcap-qe/ci/base:v2024.10.8-32-ge807718-go1.23` (already used
by tikv/tikv prow jobs)
- `hub.pingcap.net/jenkins/network-multitool` →
`wbitt/network-multitool` (upstream public image, already used in
tikv/pingcap prow jobs)

- **`pull_integration_test.groovy`**
- `OCI_ARTIFACT_HOST`: `hub-zot.pingcap.net/mirrors/hub` →
`us-docker.pkg.dev/pingcap-testing-account/hub` (Google Artifact
Registry, consistent with tiflash/ticdc latest pipelines)

ci(tidb-tools): migrate container images from hub.pingcap.net to cloud-accessible registries (#4324)

Remove all `hub.pingcap.net` image references from `pingcap/tidb-tools`
pipelines, replacing them with cloud-accessible alternatives.

## Changes

- **`pipelines/pingcap/tidb-tools/latest/pod-pull_verify.yaml`**:
- `hub.pingcap.net/jenkins/centos7_golang-1.23:latest` →
`ghcr.io/pingcap-qe/ci/jenkins:v2025.12.7-3-g1c0b8cf-go1.23`
  - `hub.pingcap.net/jenkins/mysql:5.7` → `docker.io/library/mysql:5.7`
- Removed the unused `net-tool` container (previously using
`network-multitool`)

The deprecated `jenkins/` folder is left unchanged.
