feat(desktop): Add option to disable hardware acceleration on Windows #10424

Description

Some Windows users experience rendering issues, black screens, or poor performance with the desktop app due to GPU/driver compatibility problems.

Proposed Solution

Add a settings toggle to disable hardware acceleration (GPU rendering) on Windows. This allows users with problematic GPU configurations to fall back to software rendering.

Use Cases

• Users with older or incompatible GPU drivers
• Users running in virtualized environments (VMs, RDP)
• Users experiencing visual glitches or black screens on startup

Additional Context

This is a common feature in other Electron/Tauri apps (VS Code, Discord, Chrome all have this option). The setting would add --disable-gpu flag to the WebView on Windows when enabled.
