* feat: expose KubeVirt high-performance storage features in VM and Volume UI

Adds UI to configure KubeVirt high-performance disk/storage settings that
were previously only reachable via VMBuilder/Terraform:

- Per-volume "Storage Performance Options": a performance profile
  (Default / High Performance / Custom) exposing per-disk cache, io and
  dedicatedIOThread on all disk types (VM image/root, new, existing,
  container) and on the standalone Volume form.
- VM-wide "High Performance (I/O Threads and Multi-Queue)": blockMultiQueue
  and ioThreadsPolicy (+ supplemental-pool thread count), shown only in the
  VM section since these are domain-level and cannot be set per-PVC.
- Compatibility guardrails: io=native forces cache=none; cache=none on
  Filesystem volumeMode warns; blockMultiQueue requires a virtio disk.

* fix: address review feedback on high-performance storage UI

Resolves the Copilot review comments on #1133:

- Gate the whole feature behind a new `highPerformanceStorage` release
  feature flag (v1.9.0) so older supported clusters never render the
  controls or receive unsupported KubeVirt fields.
- Force Cache Mode to "none" whenever Native I/O is selected, including
  from the "Default" ('') cache value, and disable every non-"none" cache
  option (Default included) while Native is active. Previously the empty
  cache value slipped past the guardrail and produced an invalid combo.
- Clear an already-enabled blockMultiQueue when the last virtio disk is
  removed, so a disabled checkbox can no longer persist an invalid setting.
- Strip stale cache/io/dedicatedIOThread fields from the merged disk spec
  when a regenerated disk no longer requests them, so switching a disk back
  to "Default" (or unchecking Dedicated I/O Thread) while editing no longer
  silently preserves the previous values.
- Expose the disclosure toggle's state to assistive tech via aria-expanded
  and an expand/collapse aria-label.
- Add unit tests for the profile transitions and the Native/cache guardrails.

* fix: address second-round review on high-performance storage UI

Resolves the two Copilot findings on #1133 and votdev's UX feedback on
harvester/harvester#11550:

- Restore the disk's original bus when the performance profile goes back
  to "Default". The "High Performance" preset switches the bus to virtio,
  but leaving the preset only cleared cache/io/dedicatedIOThread, so a
  SATA/SCSI disk was silently left on virtio — a bus change that can make
  an existing guest unbootable. The pre-preset bus is now remembered and
  put back, unless the user picked a different bus themselves in the
  meantime.
- Pass the VM-wide performance values from the VM detail page to the
  shared Volume component. The mixin already parsed them via
  getInitConfig(), but the detail caller never forwarded them, so
  VMPerformanceOptions fell back to its prop defaults and hid itself in
  view mode — configured blockMultiQueue / ioThreadsPolicy settings were
  invisible. They are also refreshed in the value watcher so the panel
  does not go stale.
- Make the VM-wide "High Performance" panel expandable/collapsible,
  matching the per-volume "Storage Performance Options" disclosure. It
  stays collapsed unless the VM already has something configured, so the
  average user is not faced with specialist tuning controls by default.
- Fix the unit tests to use Vue Test Utils v2 mount options. They used
  the v1 top-level `mocks` key, which VTU 2.x ignores, so every case
  failed on mount. The repo has no jest config or test script, so this
  was not caught. Add coverage for the bus save/restore behaviour.

Alejandro BonillaandVolker Theile e013534373 feat: allow Cloud Config for Windows guests (Cloudbase-Init) (#984)
* feat(vm): allow Cloud Config for Windows guests

Currently the Cloud Config editor is completely hidden when a VM's
OS Type is set to Windows, and no `cloudinitdisk` volume or secret
is written to the VM spec even if the user has entered content.

This blocks a common Windows-on-Harvester workflow: using
Cloudbase-Init to run first-boot configuration (install VMDP,
enable OpenSSH server, add authorized_keys, join a domain, run
`runcmd` steps, etc.). Users on Windows today have to hand-edit the
VM YAML after creation to attach a cloudinitdisk, which is fragile
and undiscoverable.

Changes:
- Remove the `v-if="!isWindows"` on the CloudConfig component so
  the editor is available for every OS type. The Sysprep editor
  continues to render only for Windows, so Windows now gets both
  panels; Linux is unchanged.
- Drop the `if (!this.isWindows)` guard around the cloudinitdisk
  volume serialization so the disk is attached whenever the user
  provided user-data or network-data, regardless of OS.
- Drop the `|| this.isWindows` early-return in `saveSecret` so the
  cloud-init secret is persisted for Windows VMs too.
- `getInitUserData` now returns a bare `#cloud-config\n` header for
  Windows instead of the Linux qemu-guest-agent runcmd template
  (which would fail on Cloudbase-Init). VMDP installs the QGA on
  Windows as a native service, so the runcmd path is not needed.

The "Install guest agent" checkbox stays disabled for Windows
because it specifically drives the Linux QGA-via-runcmd recipe.

Fixes point 2 of harvester/harvester#11124.

* fix(vm): do not clear cloud-config on isWindows watcher fire

The isWindows watcher runs on every change of the isWindows computed
property, including on mount when editing an existing Windows VM. Setting
this['userScript'] and this['networkScript'] to undefined at that point
wipes the cloud-config data that was just loaded from the existing VM's
cloudinit secret, so the Advanced -> Cloud Config editor shows empty
even though the VM has data on the wire.

Remove the two clears - Cloud Config is now supported for Windows guests
by this PR, so there is no reason to unset the user/network scripts when
the OS type is Windows. sshKey and installAgent remain gated (SSH keys
are injected via cloud-init on Linux only, and the qemu-guest-agent
package install checkbox does not apply to Windows).

* refactor(vm): Get CloudInit working for VM templates

- Remove unnecessary osType watcher in cloud config. The watcher (see `pkg/harvester/edit/kubevirt.io.virtualmachine/VirtualMachineCloudConfig/DataTemplate.vue`) that cleared the cloud config template for Windows VMs is no longer necessary.
- Automatically strip the CloudInit `User Data` properties `package_update` and `packages` for OS type `Windows`.
