Move GPU and USB PCIe passthrough to after OS install

Browse Source 
GPU and VL805 PCIe card passthrough (Steps 11.4/11.4b) moved to after
Ubuntu install so noVNC console works during installation. Also corrects
the Display=none instruction to happen at the same time as GPU add.

### Step 11.4b — Add USB 3.0 PCIe card to VM 100
Still in VM 100's **Hardware** tab. Click **Add** → **PCI Device**.
First, identify the card's PCI address on the Proxmox host:
```bash
lspci | grep -i usb
# Look for the PCIe card — e.g.:
# 82:00.0 USB controller: VIA Technologies, Inc. VL805/806 xHCI USB 3.0 Controller (rev 01)
```
In the dialog:
| Field | Value |
|-------|-------|
| Raw Device | selected |
| Device | 0000:82:00.0 (your address from lspci) |
| All Functions | checked |
| PCI-Express | checked |
| ROM-Bar | checked |
| Primary GPU | unchecked |
Click **Add**.
All ports on the USB card are now owned by VM 100. The Coral TPU for VM 101
(Frigate) uses one of the server's built-in rear USB ports instead — it only
needs USB 3.0 speed and works on any port.
> **VL805/VIA cards** are single-function (one PCI address), so All Functions
> has no effect but does no harm. ASMedia and other multi-function cards
> benefit from it more.
VM 100 now appears in the left panel. **Do not start it yet** — data drives
must be added first (Steps 11.6–11.8). The GPU and USB PCIe card are added
**after** the OS is installed (Steps 11.4 and 11.4b, later in this phase).

### Step 11.4 — Add GPU to VM 100
Now that Ubuntu is installed and the noVNC console is no longer needed, add
the GPU. **Shut down VM 100 first** (`sudo poweroff` inside the VM).
In VM 100's **Hardware** tab, click **Add** → **PCI Device**.
| Field | Value |
|-------|-------|
| Raw Device | select the GPU from the dropdown |
| All Functions | **checked** |
| ROM-Bar | **checked** |

Also change the Display device: **Hardware → Display → Edit → Graphic card: none**.
noVNC will stop working after this — all console access goes through SSH or
the GPU's physical output.

```bash

### Step 11.14 — Install Ubuntu Server in VM 101
Start VM 101, open the console, and work through the Ubuntu Server installer.
