🎨 Palette: Highlight real-time achievement celebrations and prevent ANSI color leaks

[aidasofialily-cmd]

💡 What:

• Appended CLR_RESET after the mode indicator ([HARD MODE] / [NORMAL MODE]).
• Styled the real-time "NEW BEST!" achievement celebration message with Bold Yellow (CLR_CTRL), sparkles (✨), and explicit CLR_RESET.

🎯 Why:

• Previously, mode indicators did not output a reset sequence, causing red or green styling to bleed into subsequent text on the HUD line.
• Highlighting real-time achievements in celebratory Bold Yellow provides clear, joyful visual feedback when players break their personal best records.
