🎨 Palette: [UX improvement] Add semantic red styling for error states in TUI footer

[omsingh02]

💡 What: Added specific styling logic to render error statuses (e.g., those containing "[!]" or "error") in bold red within the TUI footer.
🎯 Why: Previously, error statuses would incorrectly fall back to the default "success" styling (bold green). This change ensures that failure states are visually distinct and immediately recognizable to the user.
📸 Before/After: Before, a status like "[!] Voice error: ..." would be preceded by a green indicator. After, it is preceded by a red indicator.
♿ Accessibility: Improves cognitive accessibility by using semantic colors (red for errors, green for success) to convey system status, rather than relying solely on text prefixes.
