Randomize Animation Image Order Instead of Using Consecutive Sequence

[Padrecc]

This update introduces randomized ordering for the animation image frames instead of always displaying them in a fixed, consecutive sequence. At initialization, the image array is rotated by a random offset generated using Zephyr’s sys_rand32_get(), ensuring that each startup begins the animation from a different frame.

Key Improvements

• Added randomization to image sequence by applying a random rotation to the animation frame array
• Eliminated reliance on consecutive, predictable start positions
• Improved user experience by introducing visual variety on each boot
• Automatic array sizing for better maintainability
