UI: Create Backup Schedule doesn't show instance selection and fails

problem

Create Backup Schedule in UI doesn't show instance selection, passes random uuid for virtualmachineid and fails with error "Unable to execute API command createbackupschedule due to invalid value. Invalid parameter virtualmachineid value=65780f6c-c2d4-4ee7-a174-db123c28ce67 due to incorrect long value format, or entity does not exist or due to incorrect parameter annotation for the field in api cmd class."

uuid - 65780f6c-c2d4-4ee7-a174-db123c28ce67 belongs to a volume.

versions

Checked with ACS 4.22.0 RC2

The steps to reproduce the bug

1. Create Backup Repo, and Backup Offering
2. Deploy an instance and assign Backup Offering to it
3. Navigate to Backup Schedules, and Try to create schedule for the instance

What to do about it?

UI shouldn't pass any random virtualmachineid for backup schedule, and there should be provision to select the instance (with backup offering) to schedule backups.

The UI is taking the uuid of the last resource that was opened before BackupSchedules.
For resources that are not vm, an Instance selection dialog is shown.

Screen.Recording.2025-10-29.at.4.17.07.PM.mov

ui/src/views/compute/backup/CreateBackupSchedule.vue

  computed: {
    resourceType () {
      if (!this.resource) return 'none'

      if (this.resource.vmstate !== undefined ||
        this.resource.guestosid !== undefined ||
        this.resource.hypervisor !== undefined ||
        this.resource.backupofferingid !== undefined ||
        this.resource.serviceofferingid !== undefined) {
        return 'vm'
      }  

But the code above is recognizing a volume as a vm (this.resource.vmstate is set for volumes). So it is not showing the vm selection dialog.

Ideally it should not consider the old resource at all and always show the instance selection dialog.
