Add animated stars that fade in and out to sections without background images

Implements a new JavaScript function `initStars` that dynamically creates and appends circular star elements to sections with the class `.home-info`. These stars have random sizes, positions, fade animations, and durations, controlled by CSS and keyframes defined in `static/css/styles.css`. The `initStars` function is called on page load via `initPageLoadAnimation`.
