samples: add color-coded bounding boxes for multi QR code detection #29281

Improves the existing qrcode.py sample by adding color-coded bounding boxes when multiple QR codes are detected simultaneously.

Previously all QR codes were drawn with the same green color, making it hard to distinguish between them visually.

This change adds a QR_COLORS palette so each detected QR code gets a unique color, improving visual clarity for multi-QR detection.
