- Added deviceDescription computed signal using getDeviceDescription util
- Replaced device().description with deviceDescription() in template
- Updated all ixTest attributes and aria-label to use new computed signal

- Added ContainerDeviceType import to instance-disk-form component
- Replaced 'FILESYSTEM' string with ContainerDeviceType.Filesystem
- Updated test expectations to use enum value

- Changed dtype in ContainerFilesystemDevice from 'FILESYSTEM' to ContainerDeviceType.Filesystem
- Changed dtype in ContainerNicDevice from 'NIC' to ContainerDeviceType.Nic
- Changed dtype in ContainerUsbDevice from 'USB' to ContainerDeviceType.Usb
- Added exhaustiveness checking in getDeviceDescription with never type
- Removed unused containerDeviceTypeLabels import

- Updated instance-disks to filter only Filesystem devices (removed DISK/RAW)
- Updated instance-usb-devices to use direct equality check instead of includes()
- Fixed track keys in templates: changed from device.name to device.id
- Updated USB device test mocks to match new interface (usb.vendor_id/product_id)
- Fixed test expectations to match new device description format (USB xxxx:yyyy)

- Fixed track key in instance-nics template: changed from device.name to device.id
- Updated NIC device test mocks to match new ContainerNicDevice interface
- Added required fields: id, trust_guest_rx_filters, nic_attach, mac
- Updated test expectations to use nic_attach instead of name (br0/br1)

- Removed blockDeviceNameValidator (for DISK devices)
- Removed diskPathValidator (for DISK devices)
- Removed rawFilePathValidator (for RAW devices)
- Removed corresponding tests for these validators
- Removed helptext: deviceTypes.diskTooltip and deviceTypes.rawTooltip
- Removed helptext: deviceBadgeTooltips.disk and deviceBadgeTooltips.raw
- Removed validator messages: blockDeviceName, diskPathMustStartWithDevZvol, rawFilePathMustStartWithMnt
- Kept only validators/helptext for FILESYSTEM devices (containerPathValidator, poolPathValidator)

Removed unused helptext related to removed DISK/RAW device types:
- diskFormOptions (virtio, ahci, native, threads, ioUring)
- ioBusTooltip
- bootFromTooltip

Removed unused helptext items that are not referenced anywhere:
- disksLabel, disksSourceLabel, disksDestinationLabel, disksDestinationTooltip
- deviceDescriptions.unknownPath

Components use inline translations instead of these helptext constants.

The filesystemTooltip in deviceTypes object is not used anywhere.
Device tooltips are provided by deviceBadgeTooltips instead.

Fixed 4 test suites that were failing after removing DISK/RAW device types:

1. virtualization-instances.store.spec.ts: Fixed device mocks to use id and dtype
2. virtualization-config.store.spec.ts: Updated subscription expectation from 'virt.global.config' to 'lxc.config'
3. add-usb-device-menu.component.spec.ts: Added missing 'device' property to USB device mock
4. get-device-description.utilts.spec.ts: Completely rewrote tests to only cover FILESYSTEM, NIC, and USB devices

All 32 tests now passing.
