Issue:
Clone uses wrong node when identical templates exist on multiple Proxmox nodes
**Versions:**
- Telmate/proxmox 3.0.2-rc03
- Terraform v1.9.8
- Proxmox VE 8.2.2

**Environment Setup:**
Proxmox cluster with two nodes:
- `proxmox1` with storage `proxmox1-1tb` (only available on `proxmox1`)
- `proxmox2` with storage `proxmox2-1tb` (only available on `proxmox2`)

On both nodes, I have created a template VM called "vm-template". The templates are identical in name, but each is stored on the local storage of its respective node:
On `proxmox1`: `vm-template` uses `proxmox1-1tb`
On `proxmox2`: `vm-template` uses `proxmox2-1tb`

**VM Configuration file:**
```
resource "proxmox_vm_qemu" "proxmox-vm" {
  target_nodes = [
    "proxmox2",
  ]
  clone = "vm-template"
  full_clone = true
  define_connection_info = true
  disk {
        backup = true
        discard = false
        emulatessd = false
        format = "raw"
        size = "250G"
        slot = "scsi0"
        storage = "proxmox2-1tb"
        type = "disk"
    }
...
}
```

**Problem:**
When using the `clone` parameter to create a new VM from a template, and the same template exists on multiple nodes (with identical names), the provider sometimes selects the wrong node to clone from - not the one specified in `target_nodes`.

This leads to errors if the storage backing the source template is not available on the destination node:
```
Error: storage migration failed: storage 'proxmox1-1tb' is not available on node 'proxmox2'
```

Even though the destination node (`target_nodes`) already has the exact same template available locally (with the same name), the provider attempts to clone from another node - which breaks the workflow.

**Expected Behavior:**
The provider should prefer cloning from the node specified in `target_nodes`, **if the template exists there**, instead of arbitrarily selecting another node. This would avoid unnecessary storage migration errors and match user intent.

**Possible Solution:**
- Introduce an optional `clone_node` argument, allowing the user to explicitly set the source node for cloning.
- Or, if `clone_node` is not set, always prefer the node in `target_nodes` if the template is found there.


Discussion:
@Tinyblargon: @vadym-replianchuk Would you be able to test with  #1398?@vadym-replianchuk: Of course! I'll write back when I check.

**upd.** I couldn't check it@Tinyblargon: @vadym-replianchuk would you be able to test with `3.0.2-rc06`?@vadym-replianchuk: @Tinyblargon , ofc. But I [can't find](https://github.com/Telmate/terraform-provider-proxmox/tree/v3.0.2-rc06) that version, only `3.0.2-rc05`@Tinyblargon: @vadym-replianchuk Sorry, I got the numbers mixed up, meant `3.0.2-rc05`.@vadym-replianchuk: I checked my use case, the virtual machine was created without errors.
Thank you!
