Support AMD GPUs on Desktop (#7799)

Add AMD ROCm GPU option to the desktop installer

## What changed
- Add an AMD GPU choice to the installer picker with updated recommended
badge logic, logo asset, and i18n copy.
- Accept and auto-select the new `amd` device type in the install flow
when it is detected.
- Update `@comfyorg/comfyui-electron-types` and lockfile entries
required for the new device enum.

## Why
- Desktop users with AMD GPUs need a first-class install path instead of
falling back to CPU/manual options.
- This reuses the existing picker/device model to keep the change scoped
and consistent with current UX.
- Tradeoffs: torch mirror selection still falls back to the CPU mirror
for AMD until a dedicated ROCm mirror is available.
