* feat: align the storage performance options with the Rancher machine pool form
Show the storage performance profile on every volume instead of behind a
collapsible toggle, and move the VM-wide options to a plain Storage
Performance section in the Advanced Options tab. Put the Native I/O tip in
a live region so screen readers announce the cache mode change, use an
integer input for the I/O thread count, and use the same copy as the
Rancher form.
Skip the view-only backup row in the image and container volumes when it
has nothing to show, so it no longer adds an empty gap above the profile.

* fix: announce the storage performance warnings and name the virtio requirement
- Put the bus tip and the Filesystem warning in an always-rendered status
region. They appear above the field being changed, so screen readers need
them announced.
- Say in the bus tip that a dedicated I/O thread needs the virtio bus, because
KubeVirt rejects it on any other bus.
- Mark I/O Thread Count as required while editing, like the Rancher form.

* fix: state only the dedicated I/O thread requirement in the bus tip
Neither the Harvester docs nor KubeVirt tie cache mode or I/O mode to the bus,
so stop saying that those options work best on virtio.

* perf: speed up the VM list with many VMs
The VM list scanned whole store lists for every row and re-evaluated the same values per row on every render and sort. With several hundred VMs this blocked the browser on sorting and on every VM update.
Performance:
- look up launcher pods and migrations through shared indexes (namespace/name -> resource) instead of scanning per row; the indexes are computed per store list, so they stay in sync with in-place store updates
- use the same migration lookup (getLatestMigration) in the VM model and on the VM detail page
- look up PVCs, PVs, VMIs and restore backups by id
- merge VMs and VMIs with a Set
- evaluate the VM state once when sorting by state
- check the unschedulable condition before the pod based state checks
- cache feature flag results and per-schema/per-setting values that are the same for every row
Bug fixes:
- the launcher pod map was never rebuilt, because the store keeps the same array
- pods, volumes and migrations of a VM with the same name in another namespace could be picked up
The order of the volumes of a VM (vm.volumes) now follows the VM spec instead of the store order. Nothing depends on it.
Measured in a synthetic setup, 100 rows per page, sorting by state (Chrome, dev build):
- ~490 VMs, ~500 PVCs/PVs: 1.9 s -> 1.0 s
- ~490 VMs, 600 PVs, 200 migrations: 6.0 s -> 0.7 s, main thread blocked during VM updates 78% -> 32%
With few volumes the gain is much smaller (8-20%).

* fix: read VM data from the store of the resource instead of a fixed one
The migrations of a VMI and the migration badge of the state column were read from the hardcoded `harvester` store. In the Rancher explorer (embedded and standalone) the data is loaded into the `cluster` store, so a running migration was shown neither in the VM state nor as badge.
The VM model remembered the store of the current product in a module variable on first use and never updated it. The same model is used in the Harvester product (`harvester` store) and in the Rancher explorer (`cluster` store), and Rancher keeps the page loaded when going from the explorer of a Harvester cluster to Virtualization Management and into the Harvester product. The VM list then read the VMIs, launcher pods, volumes and restores from the wrong store, and running VMs were shown as Starting until the page was reloaded.
Read the data from the store the resource lives in (`this.$getters`, in the formatter the store of the current product). In the Harvester product this is still the `harvester` store, so nothing changes there.
Not covered: volume details like the lock icon of encrypted volumes. The explorer uses the generic Rancher PVC model, which does not know them, and settings based checks (feature flags, backup target) are not loaded there either.

Add an "Enable network boot (PXE)" option to bridge network interfaces and
a VM-level choice to place network boot devices before or after volumes.
The form now owns interface boot order: enabled NICs get sequential boot
orders ahead of or behind the volumes, and a stale bootOrder is no longer
inherited from the old spec.
This also fixes editing a VM whose interface bootOrder was set in YAML
(the documented workaround): the form used to renumber disks from 1 while
keeping the NIC's bootOrder, producing a duplicate that KubeVirt rejects.
The boot order shown on the VM, snapshot and backup detail pages now
includes network interfaces.

* 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.
