Aleksei Sviridkin d6b38f0a79 fix(kubernetes): fail the OIDC bootstrap Job when the tenant CA is missing (#4232)
<!-- Thank you for making a contribution! Here are some tips for you:
- Use Conventional Commits for the PR title: `type(scope): description`
- Types: feat, fix, docs, style, refactor, perf, test, build, ci, chore
- Scopes are not an exhaustive list — pick the most specific scope for
the change and extend the list when a genuinely new area appears.
Examples:
- System components: dashboard, platform, operator, cilium, kube-ovn,
linstor, fluxcd, cluster-api
- Managed apps: postgres, mariadb, redis, kafka, clickhouse,
virtual-machine, kubernetes
- Development and maintenance: api, hack, tests, ci, docs, maintenance
- Breaking changes: append `!` after type/scope (`feat(api)!: ...`) or
add a `BREAKING CHANGE:` footer
- If it's a work in progress, consider creating this PR as a draft.
- Don't hesistate to ask for opinion and review in the community chats,
even if it's still a draft.
- Add the label `kind/backport` if it's a bugfix that needs to be
backported to a previous version.

## What this PR does

In `spec.oidc.mode: System`, the post-install/post-upgrade bootstrap Job
patches the chart-owned `<release>-oidc-kubeconfig` Secret with a real
kubeconfig built from the tenant admin kubeconfig's CA data. When that
CA data was empty, the script logged a WARNING and continued, then
exited 0. The hook was satisfied, the HelmRelease reported `Ready`, and
the Secret was left holding the install-time placeholder kubeconfig,
which cannot authenticate. This PR makes the Job fail (`exit 1`)
instead, so the failure surfaces as a red install and can be retried
(the Job already has `backoffLimit: 6` and `restartPolicy: OnFailure`)
rather than reported as a falsely healthy release. This is the smallest
of the three directions raised on the linked issue, and matches how the
neighbouring failure mode in the same script already behaves (a failed
`kubectl apply` of the ClusterRoleBindings already fails the Job under
`set -euo pipefail`). Behaviour for `mode: None` and `mode:
CustomConfig` is unchanged, and the common case — CA data present — runs
the identical patch commands as before.

A regression test was added to
`packages/apps/kubernetes/tests/oidc_test.yaml` asserting the rendered
Job script contains the `exit 1` on empty `CA_DATA` and no longer
contains the old warn-and-continue text. Confirmed it fails against the
pre-fix template and passes against the fix.

Validation:
- `helm unittest .` in `packages/apps/kubernetes` — 150/150 tests pass
(up from 149 before the new test).
- `helm template ... --show-only templates/oidc-rbac-job.yaml` with
representative `System`-mode values renders valid YAML; the extracted
bootstrap script passes `bash -n` and `shellcheck -s sh` introduces no
new warnings versus the pre-change script.
- `make generate` was not run/needed — this change touches neither
`values.yaml`, `values.schema.json`, `Chart.yaml`, nor `README.md`.
- Not run: a live cluster reproduction (Kamaji-issued admin kubeconfig
actually missing CA data at Job run time). The defect is provable from
the script logic itself and the added unit test demonstrates the
fail-then-pass behaviour; there is no live cluster available in this
environment.

### Downstream repositories

<!--
Cozystack is upstream for repositories that are NOT kept in sync with it
automatically, and nothing in CI compares the two sides, so a change
here can break them silently.

Which change forces what, and which file to touch, is the trigger map in
docs/agents/contributing.md under "Downstream Repositories". Walk it
before you tick anything.

IF YOU ARE AN AI AGENT OR AN LLM, THIS IS PART OF THE TASK, NOT A FORM
TO FILL IN:

1. Walk the trigger map against the actual diff of this PR, file by
file. Do not decide from the PR title or from your memory of what you
changed.
2. For every repository you tick, open the follow-up PR there and link
it on the same line. A ticked box with no link claims work that does not
exist, which is worse than an empty box. Search that repository for an
open PR or issue covering it first, and link that instead of filing a
duplicate.
3. When the follow-up is out of scope, or needs a decision that is not
yours to make, open an issue in that repository instead, link that, and
say so in the PR body. Do not push a speculative PR into another
repository just to fill a line here.
4. Do not tick "No downstream repository is affected" to make the
checklist go away. If you are unsure, leave every box empty and say so
in the PR body, so a human decides.

follow-up:

This change is confined to the shell logic inside
`packages/apps/kubernetes/templates/oidc-rbac-job.yaml`'s post-install
hook Job (a `Values.oidc.mode: System`-only failure path) and its
accompanying helm-unittest test. It does not add, rename or remove a
package, a `values.yaml` key, a CRD, a namespace, a release-owned object
name, or any other surface the trigger map lists, so no downstream
repository is affected.

### Release note

```release-note
fix(kubernetes): a System-mode OIDC install no longer reports Ready while the tenant OIDC kubeconfig Secret still holds the install-time placeholder — the bootstrap Job now fails (and retries) instead of only logging a warning when the tenant cluster's CA data isn't available yet.
```

Fixes #3765

## Summary by CodeRabbit

* **Bug Fixes**
* OIDC setup now fails with an error if the tenant admin kubeconfig is
missing certificate authority data, rather than leaving the OIDC
kubeconfig Secret at its install-time placeholder.
