refactor(ingress)!: skip the Ingress when the HTTP Service is disabled

An Ingress that points at a Service which the chart does not render is broken by definition: the backend reference
cannot resolve and the ingress controller reports the rule as unavailable. The render condition therefore now also
requires `service.http.enabled` and lives in the new `gitea.ingress.enabled` helper, so the same rule can be reused
by other templates instead of being duplicated.

The namespace is taken from `.Release.Namespace` again. The `namespace` value is not a documented chart parameter,
and letting a single resource opt out of the release namespace breaks `helm uninstall` and Argo CD pruning, because
neither tracks objects outside the release namespace.

The `ingress.className` default changes from an empty string to `nginx`. An empty class makes the cluster fall back
to the default IngressClass, which silently produces a different result per cluster; naming the controller the chart
is tested against makes the rendered output predictable.

The scattered ingress suites are consolidated into a single `unittests/helm/ingress/ingress.yaml` that pins the
release name, namespace and appVersion, as required by the testing conventions, and covers the enable/disable matrix,
annotations, labels, TLS and a custom HTTP port.

BREAKING CHANGE: The Ingress is no longer rendered when `service.http.enabled` is `false`. `ingress.className` now
defaults to `nginx` instead of the cluster's default IngressClass. The undocumented `namespace` value no longer
applies to the Ingress.

Gitea Helm Chart — Copilot Instructions

Project Overview

Kubernetes Helm chart for deploying Gitea. Uses Go/Helm templating (templates/), YAML values (values.yaml), and includes sub-charts for PostgreSQL, PostgreSQL-HA, Valkey, and Valkey-cluster.

Build & Test

make readme            # Regenerate README.md parameter table + lint
make unittests-helm    # Run Helm unit tests (helm-unittest plugin required)
make unittests-bash    # Run bash/bats script tests (requires git submodule init)
make unittests         # Both of the above

Always run make readme after changing values.yaml @param annotations. Always run make unittests-helm after changing templates or unit tests.

Conventions

values.yaml

Use ## @param path.to.key Description annotations for every user-facing value. These drive the auto-generated README parameter table.
Property ordering within a resource block: enabled, annotations, labels first, then type-specific fields.
Top-level keys are sorted alphabetically within their section group.
Use Helm Values pattern from renovatebot. Ensure that the attributes registry, repository and tag are available as part of the dict image. For example:

image:
  registry: docker.io
  repository: library/busybox
  tag: 0.1.0

Templates

Helm templates live in templates/gitea/. Helpers live in templates/_helpers.tpl.
Use camelCase for all files and variables (e.g httpRoute, backendTLSPolicy, gatewayAPI, statefulSet).
Use include "gitea.fullname" for naming resources.
Use fail for required-value validation with clear error messages referencing the full values path.
Ensure, that the attributes annotations, labels, name and namespace are alphabetically sorted.
Render all attributes, even if they are empty, to prevent drift in Argo CD. For example, labels must be rendered, while annotations are defined as yaml:"annotations,omitempty".
Use plural for *.tpl files, because they may contain functions for multiple resources of the same kind (e.g. _services.tpl for httpService.yaml or sshService.yaml, _backendTLSPolicies.tpl for backendTLSPolicy.yaml).
Use as prefix of YAML files the resource kind (e.g., deployment.yaml for Deployment resources). If there are multiple resources of the same kind, use a descriptive suffix (e.g., deployment_metrics.yaml for a Deployment related to metrics).

Unit Tests

Helm unit tests live in unittests/helm/ mirroring the template structure.
Test files are YAML using the helm-unittest format.
Each test must set all required values explicitly — do not rely on cross-test state.
The values.yaml file must pass yamllint. The configuration is in .yamllint. Use make yamllint to run the linter.
The title of the unit test should clearly describe the scenario being tested. As title must be use a short sentence starting with a capital letter and ending without a period.
Each unit test must explicitly set a custom namespace and release name, rather than relying on defaults.

Commits & PRs

Follow Conventional Commits for PR titles and commit messages (e.g. feat:, fix:, refactor:, docs:, style:).
See CONTRIBUTING.md for full PR requirements.
Explain in detail why a change is needed, not just what the change is. Include links to relevant issues, PRs, or external references.
Add co-authors for any contributions that are not your own. Use the Co-authored-by: trailer in the commit message.

Documentation

docs/ contains topic-specific guides (e.g. gateway-api.md, ha-setup.md).
README.md parameter tables are auto-generated — never edit them manually.
