k3s kubernetes 10846d1082 fix: root-cause Flux Setters silent no-op - namespace mismatch
ImageUpdateAutomation only lists ImagePolicy objects in its own
namespace (image-automation-controller's getPolicies() scopes the
List() to obj.Namespace, confirmed by reading v1.2.4 source) - the
$imagepolicy marker's namespace:name is only used to match against
that pre-filtered list, not to broaden the search. Our
ImageUpdateAutomation lived in flux-system while its ImagePolicy
lived in hello-app, so the policy was invisible and Setters always
found zero markers to update ("repository up-to-date" forever),
regardless of correct marker syntax/RBAC/policy resolution.

Moved ImageUpdateAutomation into the hello-app namespace (alongside
its ImagePolicy), keeping a cross-namespace sourceRef back to the
flux-system GitRepository. Also fixed the commit messageTemplate,
which used the removed .Updated field (v1.2.4 requires .Changed).

Verified live: Flux pushed commit 0273f15 updating deployment.yaml's
tag on its own, and the cluster rolled out that image without any CI
involvement. Removed the update-deployment-tag CI workaround job
accordingly - it's redundant now and would otherwise race with
Flux's own commits.
