Fix Qidi start G-code ignoring the selected plate type (#16372)

# Description

With "Support multi bed types" enabled on a Qidi printer, the
first-layer bed temperature was always taken from the Smooth PEI / High
Temp Plate setting, whichever plate type was selected.

The slicer computes the right value (`first_layer_bed_temperature` in
the G-code footer follows the selected plate), but the machine start
G-code of these presets hardcoded `[hot_plate_temp_initial_layer]`:

- `fdm_qidi_x3_common` (base of X-Max 3, X-Plus 3, X-Smart 3, X-Plus 4,
Q1 Pro)
- `Qidi Q1 Pro 0.4 nozzle`
- `Qidi X-CF Pro 0.4 nozzle`

They now use `[bed_temperature_initial_layer_single]`, which follows the
selected plate type, as most other profiles do. The Qidi bundle version
is bumped to `02.04.00.17`.

With "Support multi bed types" disabled, these printers use the default
plate (Smooth PEI / High Temp Plate), so the temperature is unchanged
there.

## Tests

`python3 scripts/orca_profile_tool.py check` passes.

Sliced on Qidi X-Max 3 0.4 nozzle with "Support multi bed types"
enabled, `0.20mm Standard @Qidi XMax3`, `Generic PLA @Qidi`, with a
different bed temperature set for each plate type (first layer / other
layers).

Before, with first layer set to 50–55 °C: `M190 S54` for every plate
type.

After, a two-layer print:

| Plate type | Set (first / other) | `M190` at start | `M140` at layer 2
|
| --- | --- | --- | --- |
| Cool Plate SuperTack | 51 / 61 | 51 | 61 |
| Cool Plate | 52 / 62 | 52 | 62 |
| Textured Cool Plate | 53 / 63 | 53 | 63 |
| Engineering Plate | 54 / 64 | 54 | 64 |
| Smooth PEI / High Temp Plate | 55 / 65 | 55 | 65 |
| Textured PEI Plate | 56 / 66 | 56 | 66 |

 **Pitfall.**
-- **Rule:** On NVIDIA reach for `WEBKIT_DMABUF_RENDERER_FORCE_SHM` before
-  `WEBKIT_DISABLE_COMPOSITING_MODE`. **Why:** the proprietary driver cannot back WebKit's hardware
-  DMABUF renderer, leaving web views blank or slow; FORCE_SHM keeps accelerated compositing and only
-  skips the hardware path, while disabling compositing drops it. Threaded scrolling is a separate,
-  release-dependent default (off in 2.44/2.45, on from 2.46). `WEBKIT_DISABLE_DMABUF_RENDERER` is not a
-  substitute — it is read first, leaves the transport set empty (no compositing from 2.44 on, where the
-  X11/Wayland fallback renderers were removed) and has a reported crash path. On Debian/Ubuntu and
-  openSUSE the `isNVIDIA()` patch returns before the FORCE_SHM check, so `WEBKIT_FORCE_DMABUF_RENDERER=1`
-  must clear it first; that variable exists only in those patches. WebKit reads all of these once per
-  process, before the first WebView.
-  The test is `/proc/driver/nvidia/version`, so a hybrid laptop that renders on its iGPU also takes the
-  shared-memory path, which is a per-frame GPU readback rather than zero-copy; exporting
-  `WEBKIT_DMABUF_RENDERER_FORCE_SHM=0` in the environment restores the hardware path.
-  ```cpp
-  // Wrong: kills compositing and threaded scrolling (and can crash on modern WebKit)
-  ::setenv("WEBKIT_DISABLE_DMABUF_RENDERER", "1", false);
-  // Right: keep compositing, skip only the hardware DMABUF path
-  if (::access("/proc/driver/nvidia/version", F_OK) == 0 && WebView::SupportsForceSharedMemory()) {
-      ::setenv("WEBKIT_DMABUF_RENDERER_FORCE_SHM", "1", /*replace*/ false);
-      ::setenv("WEBKIT_FORCE_DMABUF_RENDERER", "1", /*replace*/ false);

-  Cite: WebKit 2.52.6 `Source/WebKit/UIProcess/gtk/AcceleratedBackingStore.cpp`
-  (`rendererBufferTransportMode()`), Debian `disable-nvidia-dmabuf.patch`, WebKit bug 262607.
 - **Rule:** Set `WEBKIT_DISABLE_COMPOSITING_MODE` only on the default path in Wayland sessions,
   non-replacing (`setenv(..., false)`, so a value the user already exported wins), before GTK
-  initialises; never unconditionally, and only for the WebKitGTK releases that need it (older than

-  **Why:** WebKit2GTK accelerated compositing could fail silently under XWayland before 2.42, leaving

-  so applying it on a newer WebKit needlessly drops both GPU compositing and async scrolling (the
-  Device tab loses its smoothness); without the JS timeout the user is stuck when the signal is lost.
