Pull Request: Windows Support, Multi-Account Grid View, and Privacy Enhancements

🚀 Overview

This PR introduces significant features aimed at improving cross-platform compatibility and privacy for power users. Key additions include full Windows build support, a new Grid View for managing multiple accounts simultaneously, WebRTC IP-leak protection, and per-account proxy configurations.

✨ Detailed Changes

🏁 1. Windows Compatibility & Build System

• Asset Bundling: Updated ZapZap.spec to correctly bundle translations (po), UI files, and the new webrtc_shield.js for Windows builds.
• Build Scripts: Enhanced run.py with a new --windows build target.
  • Added automatic UI compilation using pyuic6 on Windows.
  • Configured PyInstaller to generate a windowed (GUI) executable.
• Platform Helpers: Introduced zapzap/platform/ to handle cross-platform pathing and detection more reliably.

🖼️ 2. Multi-Account Grid View

• Account Overview: Added a new "Grid View" button to the sidebar that displays all active WhatsApp sessions in a visual grid.
• Thumbnail Generation: Implemented a caching system that captures snapshots of each WebView upon switching, ensuring the grid always shows the last-seen state of each account.
• Smart Layout: Implemented dynamic grid logic that automatically calculates optimal rows and columns based on the number of active accounts.
• Quick Switching: Clicking any thumbnail in the grid instantly switches focus to that specific account.

🛡️ 3. Privacy: WebRTC Shield

• IP Masking: Created webrtc_shield.js, a specialized shim that overrides the browser's RTCPeerConnection API to prevent the leaking of local and public IP addresses.
• Script Injection: Updated WebView.py to inject the shield immediately upon document creation across all subframes.
• Control: Added a global "WebRTC Shield" toggle in the Network/Privacy settings page.

🌐 4. Per-Account Proxy Support

• Granular Control: Redesigned the Network settings UI in PageNetwork.py to include an account selector.
• Identity Isolation: Updated ProxyManager.py to store and retrieve proxy settings using a per-account prefix. This allows users to assign a different proxy (or none at all) to each WhatsApp instance individually.
• Switching Logic: The Browser controller now triggers a proxy update whenever the active account is switched, ensuring traffic is routed correctly for the visible session.

🛠️ Testing Performed

• Windows Build: Verified that python run.py build --windows generates a functional executable in the dist/ folder.
• WebRTC Leak Test: Confirmed using browserleaks.com/webrtc that real IPs are masked when the shield is enabled.
• Grid Navigation: Verified smooth transitions between the standard sidebar view and the grid layout.
• Proxy Isolation: Confirmed that proxy settings for one account do not affect the connectivity of others.

A very significant change. I'm reviewing it very calmly and cautiously, but so far I haven't found any problems for me to reject your PR.

Thank you very much for the contribution.
