fix(linux): disable WebKitGTK hardware acceleration to prevent white screen (#986)

Browse Source 
On some Linux systems with AMD GPUs (e.g., AMD Cezanne/Radeon Vega),
WebKitGTK's GPU process fails to initialize EGL, causing the app to
show a white screen on startup.

Root cause: `amdgpu_query_info(ACCEL_WORKING)` returns EACCES (-13),
which causes EGL display creation to fail with EGL_BAD_PARAMETER,
crashing the GPU process.

Fix: Use WebKitGTK's `set_hardware_acceleration_policy(Never)` API to
disable GPU acceleration on Linux, falling back to software rendering.
This is applied at startup via Tauri's `with_webview` API.
