unkinben c0c3eb4f66 Force Replace sync for the Recreate puppet master to clear stale rollingUpdate (#349)
## Why

ArgoCD fails to sync the puppet app with:

    Deployment.apps "puppetserver-master" is invalid:
    spec.strategy.rollingUpdate: Forbidden: may not be specified when strategy type is 'Recreate'

The manifest is already correct: #341 changed the master to `spec.strategy.type: Recreate` with no rollingUpdate block. The failure is a live-object artifact. When the master ran RollingUpdate the API server defaulted `spec.strategy.rollingUpdate` (maxSurge/maxUnavailable) onto the object. That defaulted field is owned by no applier, so neither a client-side merge nor server-side apply drops it when the desired manifest omits it. The live object therefore keeps `rollingUpdate` while gaining `type: Recreate`, which the API server rejects — blocking every sync.

k8s forbids any `rollingUpdate` field when `strategy.type` is `Recreate`; the two are mutually exclusive, so the sync cannot converge until the stale field is removed from the live object.

## Changes

- Annotate the `puppetserver-master` Deployment with `argocd.argoproj.io/sync-options: Replace=true`. Replace performs a full PUT that overwrites the whole object, dropping the stale `rollingUpdate` field and letting the Recreate strategy apply cleanly. The annotation is scoped to this one resource, so puppetdb/puppetboard/compiler keep the app-wide ServerSideApply behaviour.

## Validation

- `kustomize build --enable-helm apps/overlays/au-syd1/puppet` renders `puppetserver-master` with `strategy: { type: Recreate }` (no rollingUpdate) and the new sync-options annotation.
- `make kubeconform`: puppet overlay 34/34 valid; only the known cattle-system rancher kubeVersion incompatibility fails.
- `pre-commit`: all hooks pass.
