## What happened

After the laptop wakes from suspend while the session was already locked, the Omarchy lock screen (Quickshell `lock` plugin) shows only the bare password input field — no background image, no blur, none of the normal lock screen styling. The password field still works, but the screen otherwise looks broken/unstyled until unlock.

## What I expected

The lock screen to render normally on wake: themed background with blur behind the password field, same as it looks right after locking.

## Steps to reproduce

1. Lock the session (idle timeout or manual lock) so the Quickshell lock screen is showing normally.
2. Suspend the laptop (lid close or `systemctl suspend`) and let it resume.
3. Observe the lock screen after wake: bare password box on a blank background, no blur/wallpaper.

## Root cause (best guess from source reading)

In `shell/plugins/lock/LockView.qml`, the lock background is a QML `Image` loaded with `cache: false`:

```qml
Image {
  id: wallpaper
  source: root.loadBackground ? root.fileUrl(root.backgroundPath) : ""
  ...
  cache: false
}
```

`fileUrl()` appends `?v=<backgroundVersion>` as a cache-buster, but `backgroundVersion` is only incremented in `Service.qml` when the *background path itself* changes (new theme/background selected) — never on wake/resume:

```qml
if (next !== root.backgroundPath) {
  root.backgroundPath = next
  ...
  root.backgroundVersion += 1
}
```

The wake handler, `runWake()` in `Service.qml`, only starts `omarchy-system-wake` (restores brightness) and resets the idle-blank timer — it never touches `backgroundVersion` or forces the `Image` to reload:

```qml
function runWake() {
  if (!wakeProcess.running) wakeProcess.running = true
  if (lockRequested) armBlankTimer()
}
```

If the GPU-decoded texture for that `Image` is dropped across a real suspend/resume cycle (plausible with `cache: false` + i915 DRM context reset), nothing tells the `Image` to reload on wake, leaving the wallpaper blank while the rest of the lock UI (password field) renders fine.
