Fix macOS Bluetooth permissions by adding proper entitlements

- Create separate bitchat-macOS.entitlements file with com.apple.security.device.bluetooth
- Update project.yml to use the macOS-specific entitlements for the macOS target
- Regenerate Xcode project with proper entitlements configuration

This fixes the 'Bluetooth unsupported' issue on macOS which was caused by missing
device.bluetooth entitlement required for sandboxed apps
