Fix tooltip truncation for buttons and badges in New Architecture

[Copilot]

Problem

Tooltips were being truncated when hovering over various UI elements throughout the React Native Gallery application, affecting user experience and accessibility. The truncation occurred on:

• Copy to Clipboard buttons (in example code sections and throughout the app)
• Navigation menu Expand/Collapse button
• Core Component badges and other informational badges
• Page scroller left/right navigation buttons
• Documentation hyperlinks

Users could not see the full tooltip text, which violated accessibility guidelines (MAS 1.4.13 – Content on Hover or Focus) and created confusion about button purposes.

Root Cause

React Native Windows tooltips use the XAML ToolTip control, which has a default maximum width constraint. When tooltip text exceeded this default width, it would truncate in the middle of words or even characters, rather than wrapping to multiple lines.

Solution

Added tooltipProperties={{MaxWidth: 500}} to all components using tooltips in the New Architecture version only. This Windows-specific prop passes the MaxWidth property to the underlying XAML ToolTip control, allowing tooltips to expand up to 500 pixels wide before wrapping text. This prevents truncation while maintaining reasonable tooltip dimensions.

Changes

Modified 5 component files in the New Architecture version:

New Architecture:

• NewArch/src/components/CopyToClipboard.tsx - Copy to clipboard button
• NewArch/src/components/Badge.tsx - Core Component and other badges
• NewArch/src/components/ScreenWrapper.tsx - Navigation menu expand button
• NewArch/src/components/PageScroller.tsx - Scroll navigation buttons
• NewArch/src/components/Controls.tsx - Documentation hyperlinks

Each change adds a single line to set the tooltip properties, following the existing code patterns.

Testing

• ✅ Changes applied only to NewArch directory as requested
• ✅ Changes are minimal and surgical
• ✅ Follows existing code style and patterns

Impact

This fix improves the New Architecture version:

• Accessibility: Meets MAS 1.4.13 guidelines for content on hover/focus
• User Experience: Users can now read complete tooltip information
• Usability: Eliminates confusion about control purposes

Fixes #704
