[platform] Better migration for 0.36.2->0.37.2+ (#1521)

Browse Source 
## What this PR does

For users upgrading from 0.36.2 directly to 0.37.2+, where the
lineage-controller-webhook is broken out of the Cozystack controller
into a separate daemonset, the existing migration script of 0.36->0.37.0
is insufficient. This patch ensures the presence of the new version of
the lineage webhook and fixes a bug in the migration script where the
readiness of the webhook was not appropriately verified.

### Release note

```release-note
[platform] Improved migration script when skipping versions 0.37.0 and
0.37.1 during upgrades.
```

## Summary by CodeRabbit

* **New Features**
* Automatically installs the lineage-controller webhook via Helm during
setup, aligning its deployment with existing controller components.

* **Chores**
* Adds a temporary namespace for preflight validation of the webhook
service to avoid cluster-wide side effects.
* Replaces cluster-scoped dry-run checks with namespace-scoped dry-run
and ensures cleanup and timeout-based waits for predictable
installation.
