Subject: [PATCH] Fix: TextField gray overlay when iOS app runs on macOS

Issue: When the iOS app is downloaded from the Mac App Store and run on
Apple Silicon Macs, a gray overlay appears over TextField components when
Increase Contrast accessibility setting is disabled.

Reproduction:
1. Download bitchat iOS app from Mac App Store
2. Run on Apple Silicon Mac
3. Disable 'Increase Contrast' in System Settings > Accessibility > Display
4. Focus on text input field - gray overlay appears

Fix: Use ProcessInfo.processInfo.isiOSAppOnMac runtime detection to disable
autocorrection only when iOS app runs on macOS. This targets the exact
environment where the issue occurs while preserving normal autocorrection
behavior for iPhone/iPad users.

Addresses code review feedback about incorrect conditional compilation.
