fix: em dash rendering in StagingBanner component

[FSM1]

Summary

Fixed the rendering of the em dash character in the StagingBanner component by wrapping it in a string literal to ensure proper display.

Changes

• Wrapped the em dash Unicode character (\u2014) in quotes within the JSX expression in the StagingBanner component
• This ensures the em dash is properly rendered as a string rather than being interpreted as a raw Unicode escape sequence

Details

The em dash character in the staging banner message was changed from \u2014 to {'\u2014'} to maintain consistency with how other Unicode characters (the warning symbols \u26A0) are handled in the same string. This guarantees proper rendering across different environments and browsers.
