CLID-577: Onboard openshift/mirror-gui to Prow CI (openshift#77766)

* CLID-577: Onboard openshift/mirror-gui to Prow CI

Add CI configuration for the mirror-gui repository with container
image builds and test jobs for linting and unit tests.

Signed-off-by: Alex Guidi <aguidi@redhat.com>

* Fix ci-operator config: add OWNERS, catalog tests, fix test_binary

- Add OWNERS files to config and jobs directories (fixes ci/prow/owners)
- Replace test_binary_build_commands (container-run.sh fails in CI pods)
  with npm ci && npm run build to create pipeline:test-bin image
- Switch all tests to from: test-bin (npm ci runs once, not per-test)
- Add audit-catalog and catalog-integrity test jobs
- Regenerate presubmit job definitions

* fix: add lgtm to mirror-gui Prow plugin list

The lgtm plugin is configured at the top level but was missing from the
repo plugins list, which would prevent the /lgtm command from working on
openshift/mirror-gui PRs. Tide requires the lgtm label for merge.

Made-with: Cursor

* revert: remove duplicate lgtm plugin from repo config

The lgtm plugin is already enabled at the openshift org level. Adding it
to the repo-specific plugins list causes a "duplicated plugin" error in
Prow config validation.

* fix(ci-operator): use project_image build root for mirror-gui

The previous from_repository configuration expected a repo-local
.ci-operator.yaml with an imagestream reference, which does not match our
Dockerfile-based build root setup. Switch to the documented project_image
mode so ci-operator builds the root image from
.ci-operator/build-root/Dockerfile.

Made-with: Cursor

* fix: regenerate Prow jobs after project_image switch

Adds decoration_config.skip_cloning: true to all mirror-gui jobs,
required when build_root uses project_image mode.
