🎨 Palette: Semantic Error Colors in TUI

[omsingh02]

💡 What:
Added semantic red color styling to the TUI footer when the status indicates an error (e.g., contains "[!]" or "error").

🎯 Why:
Previously, if a status message did not explicitly match "Listening" or "Processing", it defaulted to a green status indicator, even for failures like [!] Recognition error: .... This gave confusing visual feedback. Now, errors are rendered in bold red, providing clear semantic cues for the user.

📸 Before/After:
Before: Errors showed up with a green circle and cyan border.
After: Errors show up with a red circle, red text, and red border.

♿ Accessibility:
Improves color-coded feedback accessibility, ensuring users immediately recognize destructive or failed actions through correct semantic coloring instead of conflicting success indicators.
