Aleksei Sviridkin d61db784a6 fix(mariadb-operator): derive the cluster name from the platform domain (#5123)
<!-- 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

Fixes #2348.

`packages/system/mariadb-operator/values.yaml` pins
`mariadb-operator.clusterName: cozy.local`, and the vendored chart turns
it into the operator's `CLUSTER_NAME` and into a SAN of the webhook
certificate. On a platform installed with any other
`networking.clusterDomain`, the operator resolves its own pods as
`<name>.<ns>.svc.cozy.local` and gets NXDOMAIN. Observed on a cluster
with `clusterDomain: lab.local`: a 2-replica MariaDB never gets
replication configured (`status.replication` stays `{}`, the secondary
runs as a standalone semi-sync master), and User, Database and Grant
fail with `lookup mariadb-<name>-primary.<ns>.svc.cozy.local ... no such
host`, while the operator only retries at verbosity 1.

`clusterName` is a value of the vendored subchart, which the `_cluster`
lookup used by package templates cannot reach. The platform now carries
`networking.clusterDomain` under the `mariadb-operator` subchart key in
the shared `cozystack-values` Secret, the same route
`keda.clusterDomain` and `opensearch-operator.manager.dnsBase` already
take. The literal in the package stays as the fallback for a render
without that Secret, so a cluster on `cozy.local` renders exactly as
before.

Tests cover both ends of the path:
`packages/core/platform/tests/apps_mariadb_operator_cluster_name_test.yaml`
pins that the Secret carries the domain under the anchored subchart key
and tracks a non-default value (it fails with the `apps.yaml` change
reverted), and
`packages/system/mariadb-operator/tests/cluster_name_test.yaml` pins
that a domain set on that key reaches the operator's `CLUSTER_NAME` and
the webhook certificate, with `cozy.local` kept as the standalone
default. `make helm-unit-tests` passes locally.


### Screenshots

<!-- REQUIRED for UI changes: attach screenshots or screen recordings
demonstrating
the visual impact of your changes. PRs with UI changes without
screenshots will not be merged. -->

### 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.

```release-note
fix(mariadb-operator): the MariaDB operator now uses the platform's networking.clusterDomain instead of a hard-coded cozy.local, so replication and User/Database/Grant reconciliation work on clusters with a non-default cluster domain.
```

## Summary by CodeRabbit

* **New Features**
* MariaDB now uses the configured networking domain as its cluster name
and webhook certificate address. If no custom domain is configured, it
continues to use the default cluster name and address.
* **Tests**
* Added coverage for default and custom domain settings, including their
effect on the MariaDB cluster name and webhook certificate address.
