#720
## Description of change
Pass `VK_F4` sys-key messages through to `DefWindowProc` before ImGui
ingestion, restoring the normal Alt+F4 -> `WM_CLOSE` ->
`launcher::shutdown()` path.
## Testing
- [x] Launch `spicecfg` (D3D9 default path) and press Alt+F4; window
closes and process exits
- [x] Launch `spicecfg` (software path) and press Alt+F4; window closes
and process exits
- [x] Close via title-bar X; still works
## Description of change
**Configurator (spicecfg.exe)**
- Attempts to create a D3D9 device on startup and uses the hardware
ImGui DX9 path when successful; falls back to the existing software
rasterizer automatically if D3D9 init fails.
- Rewrites the configurator window loop: refresh-rate-aware render
timer, minimize/resize/`WM_DISPLAYCHANGE` handling, direct Win32 ->
ImGui input (keyboard, mouse, wheel), and optimized software painting
via `SetDIBitsToDevice` instead of per-frame GDI `HBITMAP` allocation.
**Overlay / input (scoped to standalone configurator)**
- Skips expensive per-frame rawinput polling in
`ImGui_ImplSpice_NewFrame` when `CONFIGURATOR_STANDALONE` is set (Win32
messages drive input instead).
- Adds software-renderer idle-frame detection (`sw_pixels_dirty` +
draw-data hash) so spicecfg only repaints when pixels actually change.
- Adds `ImGuiWindowFlags_NoScrollWithMouse` on the configurator root
window to prevent scroll jolt on non-scrollable child widgets.

## Description of change
Closing spicecfg was blocked for up to ~495 ms. Runtime behavior is
unchanged: same flush interval and same output path during normal
operation. Only shutdown teardown is faster.
## Testing
Opened and closed spicecfg.exe repeatedly; the window closes immediately
with no hang

Save config xml once instead of ~33 times
## Testing
xml is still saved properly

## Description of change
Saving patches to file used to rewrite the file repeatedly, now it loads
and saves only once. Original file timestamp is now preserved on the
backup.
## Testing
Saved a very large patch set that used to take 10+ seconds; now it is
instant. Confirmed hex diffs are still accurate.

## Description of change
When opening the patches tab by pressing F4 in game, the Save button
doesn't appear until after initially selecting/deselecting a patch, then
it shifts all of the patch text below. To solve this annoyance, this
keeps the Save button in a fixed position (starts greyed out until a
selection) and no longer shifts the text.
## Testing
Confirmed saving selected patches still works properly in the overlay
and standalone cfg

## Description of change
Add `-icmphook` option under spicecfg Development/Network for emulating
keepalive ping replies in user mode, so games do not need to open
privileged raw ICMP sockets. This makes connecting to networks possible
on macOS under Whisky, and on Windows with ICMP firewalled or spice
running without Administrator privileges.
## Testing
Tested DDR and SDVX on Windows 10 and macOS Tahoe. Network check status
in test menu shows `CONNECTED` when -icmphook is enabled, and `NOT
CONNECTED` when it is disabled. Actual network functionality works as
expected (under previously impossible conditions).
